1.21kg/m3 at 20 deg C at sea level
1.16kg/m3 at at 30 deg C
Depends how hot it is and at what altitude, it is not constant. Here is a rough idea.
1 cubic foot of iron, at room temperature would weigh approx 2190 newtons.
At room temperature and 1 atmosphere, the mass of one cubic metre of water is 0.998 207 1 tons.
The room that you are in.
At 4 deg C and a pressure of 1 atmosphere, the mass is 0.999972 kilograms. At this temperature, water is at its most dense. At room temperature (20 deg C) the mass is 0.9982071 kg. The weight will, of course, depend on where on earth (or elsewhere) the weight is measured.
We can answer that, but the answer isn't simple. Try to stay with us here:First of all, it depends on the temperature, pressure, and humidity of the air.For dry air at a temperature of zero Celsius (32 Fahrenheit) and pressure of760 mm Hg, the density is1.2929 gram per liter = 1.2929 kilogram per m3 .The weight of 1.2929 kilogram is 12.67 newtons (2.85 pounds). (rounded)BUT . . . . .Don't forget that anything surrounded by a fluid is buoyed up by a force equal tothe weight of the displaced volume of fluid. So our cubic meter of air is buoyed upby a force equal to the weight of a cubic meter of air, and winds up weighing zero !Surrounded by vacuum, it weighs about 2.85 pounds. But surrounded by more air,it weighs exactly nothing.Which is why every cubic meter of air in the room doesn't fall down on the floor.

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

You dont. A cubic meter is a measure of volume. A ton is a unit of weight. How do you convert the size of a class room to a ton? You don't. Now how do you covert the weight of a cubic meter of water to a ton? That would be a question that has an answer. A cubic meter of water weighs 1000 kg, or a metric ton. A Kilogram is equal to about 2.2 pounds. So a metric ton is equal to about 2200 poins or about 1.1 tons. A cubic meter of water weighs about 1.1 tons.
The density of plutonium at room temperature is 19,816 g/cm3.

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.
A cubic foot of lead will weigh about 321 kg at room temterature, or about 708 pounds.
