First, calculate the molar mass of MgCl2:
Mg: 1 x 24.30 = 24.30
Cl: 2 x 35.45 = 70.9
24.30 + 70.9 = 95.2g/mol
Mole = Mass / Molar Mass
2.70 moles = Mass / 95.2 g/mol
Mass = 2.70 mol x 95.2 g/mol
Mass = 257.04g

Answer:
The pressure would increase because the volume of space the gas takes up decreases once the bottle is squeezed. There is less room for the gas particles to move around meaning more collisions between the particles occur.
