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
