I can =335ml
2cans=?
2cans×335ml÷1
= 670ml
The pressure of gas will increase because gaseous state is the final state and even if the heat added is evaporating some more gas is still added. It also depends on the temperature of heat added, if the temperature doesn't change the it's most likely for the pressure to be stable...
Hope it helps
The volume at 100 mmHg : 0.656 L
<h3>
Further explanation</h3>
Boyle's Law
<em>At a constant temperature, the gas volume is inversely proportional to the pressure applied </em>

V₁=3.5 L
P₁=2.5 kPa=18,7515 mmHg
P₂=100 mmHg
