A 515cm^3 flask contains 0.460 g of a gas at a pressure of 153 kPa and a temperature of 322K. What is the molecular mass of this gas

Molecular mass,

Explanation:

Given that,

Mass of gas, m = 0.46 g

Volume of the container, V = 515 cm^3

Pressure, P = 153 kPa

Temperature, T = 322 K

We need to find the molecular mass of this gas. We know that,

PV =nRT

n = no of moles

No of moles = mass/molecular mass

Let molecular mass is M

So, the molecular mass of this gas is
