1.21kg/m3 at 20 deg C at sea level 1.16kg/m3 at at 30 deg C
At room temperature and 1 atmosphere, the mass of one cubic metre of water is 0.998 207 1 tons.
1:At room temperature water is in liquid state. 2:It can conduct electricity 3:it does not have fixed shape
At room temp 1 cubic Meter of water weighs 1 Metric tonne
65 million.
Assuming pure water, at room temp, the density of water is approx 1g/ml A m3 of water is 1000 liters. As a ml in this is equal to a gram, a litre will be equal to a kg. The asnwer in this case is 1000kg.
Its volume is 1 cubic centimeter or 1 cm3. Cubic centimer is a measurement of volume.One cubic centimeter of gold has a mass of about 19.32 g at room temperature.
Assuming density is 1 gram/cc Answer = 28.33 grams
Air has an approximate molar mass of (28x.8 + 32x.2) = 28 + .2x4 = 28.8 g/mole 1 mole of gas at STP occupies 22.4 L = 22400 cm3 = 0.0224 m3 So 28.8 g/mole x 1 mole/.0224 m3 = 1286 grams per cubic meter at STP If you take 'normal temperature' to be room temperature of about 20 degrees C then 1286 x (273/293) = 1198 grams per cubic meter at standard pressure and 20 C
The room that you are in.
1 cubic inch = 16,387 06 cm3 The density of uranium is ca. 19,05 g/cm3 312,173 493 grams is the mass of a cubic inch of pure U metal at room temperature.
Each mole has a volume of 22.4 liters and a mass of 28.97g/mol at STP, therefore a cubic meter of air is 1.293 kg at 0o Celsius on the coast. An average mass of 1.2kg per m3 at room temperature and standard pressure is often used as a rule of thumb.
In this problem air mass would be dependent on its density at a given temperature and pressure. Assuming a room temperature of 20 degrees Celsius and 1 atm of pressure the density of air is 1.20 kilograms per cubic meter. 3000-square feet equals 278.7 cubic meters. Changing from kilograms to pounds equals the answer of .167 short tons.
