Answer:
Pressure exerted is 7.24 atm
Explanation:
Let's apply the Ideal Gases Law:
P . V = n . R . T
First of all, we must convert the mass to moles, to know the total moles of the mixture:
2.8 g . 1 mol / 2g = 1.4 moles of H
6.1 g . 1mol / 28 g = 0.218 moles of N
Total moles = 1.4 + 0.218 → 1.618 moles
P . 10 L = 1.618 moles . 0.082 L.atm/mol.K . 546K
P = (1.618 moles . 0.082 L.atm/mol.K . 546K) / 10 L
P = 7.24 atm
