The density of water is the weight of the water per its unit volume, which depends on the temperature of the water. So if you had a different, irregular piece of aluminum that weighed 550g and displaced 204mL of water in a graduated cylinder, then your equation would be ρ = 550g/204mL = 2.7g/mL.
you can calculate mass and volume fairly easily.
A standard table lists the values for the density of liquid water. The total mass of the water in the tank can be calculated, See also hydrostatic pressure in water and energy stored in hot water. What Is the Difference Between Density and Specific Gravity? In the Imperial system the mass unit is the slug [sl], and is derived from the pound-force by defining it as the mass that will accelerate at 1 foot per square second when a 1 pound-force acts upon it: 1 [lbf] = 1 [sl] * 1 [ft/s2] and 1 [sl] = 1 [lbf]/1 [ft/s2], The density of water is 1.940 sl/ft3 at 39 °F (4 °C), and the specific weight in Imperial units is, γ = 1.940 [sl/ft3] * 32.174 [ft/s2] = 1.940 [lbf]/([ft/s2]*[ft3]) * 32.174 [ft/s2] = 62.4 [lbf/ft3], See more about the difference between mass and weight. Please read AddThis Privacy for more information.
Ice is less dense than liquid water, so it floats.
The usual value used in calculations is 1 gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm 3).). The density of water depends on temperature and pressure as shown below: See Water and Heavy Water for thermodynamic properties at standard condtions.See also other properties of Water at varying temperature and pressure: Boiling points at high pressure, Boiling points at vacuum pressure, Dynamic and kinematic viscosity, Enthalpy and entropy, Heat of vaporization, Ionization Constant, pKw, of normal and heavy water, Melting points at high pressure, Prandtl number, Properties at Gas-Liquid Equilibrium Conditions, Saturation pressure, Specific gravity, Specific heat (heat capacity), Specific volume, Thermal conductivity, Thermal diffusivity and Vapour pressure at gas-liquid equilibrium.For other substances, see density and specific weight of acetone, air, ammonia, argon, benzene, butane, carbon dioxide, carbon monoxide, ethane, ethanol, ethylene, helium, hydrogen, methane, methanol, nitrogen, oxygen, pentane, propane and toluene.Density of crude oil, Density of fuel oils, Density of lubricating oil and Density of jet fuel as function of temperature. Note that water can be supercooled and remain a liquid well below its normal freezing point. Note that these water density values are only true for pure water. Density is the mass per unit volume of a substance.
While you can round the density to 1 gram per milliliter, there are more precise values for you to use. From the table above the density of water at 190°F is 966.8 kg/m3. So, 1g/1cm3 = 1 g/cm3, giving water its easy-to-remember density. We've got you covered! What Is the Density of Water? For regular objects (those whose faces are standard polygons, such as squares, rectangles, triangles, etc.) Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue colour. You can look at the chart in the next section to see how water's density changes with temperature. So know you know what the density of water is at different temperatures, but what if you want to find the density of something that isn't water? You can target the Engineering ToolBox by using AdWords Managed Placements. The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume.

So the density of aluminum is 2.7g/cm3, and this is true for any piece of (pure and solid) aluminum, no matter what its size is. Pure water has its highest density 1000 kg/m 3 or 1.940 slug/ft 3 at temperature 4°C (=39.2°F).. Check out our top-rated graduate blogs here: © PrepScholar 2013-2018.
To convert from density in kg/m3 to other density units - or between units - use the converting values below: 1 kg/m3 = 1 g/l = 0.001 kg/l = 0.000001 kg/cm3 = 0.001 g/cm3 = 0.99885 oz/ft3 = 0.0005780 oz/in3 = 0.16036 oz/gal(UK) = 0.1335 oz/gal(US liq) = 0.06243 lb/ft3 = 3.6127x10-5 lb/in3 = 1.6856 lb/yd3 = 0.010022 lb/gal(UK) = 0.008345 lb/gal(US liq) = 0.00194032 sl/ft3 = 0.0007525 ton(long)/yd3 = 0.0008428 ton(short)/yd3, See also density converterExample 2: Water Density in unit oz/in3Water density at temperature 20oC is 998.21 kg/m3 (table above).

Seawater density is typically slightly higher than the density of pure water, about 1.02g/cm3 to 1.03g/cm3. Pure water has its highest density 1000 kg/m3 or 1.940 slug/ft3 at temperature 4°C (=39.2°F). The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. These variations in density are very slight though, so unless you need to know very exact calculations or the experiment takes place in an area with an extreme temperature/pressure, you can continue to use 1 g/cm3 for water density.

The mass of an object is simply how much it weighs, and all regular polygons have an equation for determining their volume based on their length, width, and height.
