Answer 2

Given:

Mass of $H_2$ = 4g

Pressure (P) = 4 atm

To find:

Volume of 4g of $H_2$ = ?

Formula to be used:

pV = nRT

where:

p- pressure

V - Volume

n - no. of moles

R - Constant with value 0.082

T - Temperature at STP which is 273K

Calculation:

Number of moles of $H_2$ (n)= $\frac{given mass}{molar mass} = \frac{4}{2}=2$

Substituting the values in the following formula, gives

pV = nRT

V = $\frac{nRT}{P}$

V = $\frac{2\times 0.082\times 273}{4}$

V = $\frac{44.772}{4}$

V = 11.193

Conclusion:

The volume of 4g of $H_2$ at 4 atmosphere 11.193 L.
