The total pressure inside the balloon : 62.1 atm
Further explanation
Given
2 g of H2 gas (MM= 2g/mol)
16 g of Ne gas (MM= 4g/mol)
2 L balloon at 30'C
Required
The total pressure
Solution
mol H2 :
= mass : MM
= 2 : 2
= 1
mol Ne :
= 16 : 4
= 4
Total mol of gas = 5
T = 30+273 = 303 K
Ideal gas law :
P = nRT/V
P = 5 moles x 0.082 L.atm/mol.K x 303 K / 2 L
P = 62.1 atm
