Question

A quantity of 0.22 gram of gas occupies a volume of 112 ml at pressure of 1 atm and temperature of 273k . The gas may be :

Answer 1

Since one mole of a gas occupies 22.4 L at standard temperature (273 K) and pressure (1 atm), it is possible to arrive at a mathematical expression to relate moles, pressure, temperature and volume. This expression is called the ideal gas law.

Answer 2

We know that at STP, 1 mole of gas occupy 22.4 l

So, 0.22/x moles = 0.112/22.4

=> x = 44g

So, the gases can be Nitrous oxide, carbon dioxide, propane.
