Asample of n2o gas has a density of 2.85 g> l at 298 k. what is the pressure of the gas (in mmhg)?

To answer this item, we are to assume that dinitrogen oxide is an ideal gas such that it follows the equation,

    PV = nRT

Taking into account the density of the gas,

    P = (m/M)RT/V

Substituting the known values,

   P = (2.85 g/L)(0.0821 L.atm/mol K)(298 K) / 44 g/mol)

       P = 1.58 atm

Each 1 atm is equal to 760 mmHg

1204.38 mmHg

The air is going to come out because of the low pressure.

High-energy and unstable.
