A sample of a gas at 0.63 atm occupies a volume of 324 mL. If the temperature remains constant, what will be the new pressure if the volume increases to 124 mL?

new pressure=_____atm

umm i think in the problem, you mean "the volume DECREASES",,

assuming the gas ideal, we can use the formula
P1*V1 = P2*V2
where
P1 = initial pressure
V1 = initial volume
P2 = final pressure
V2 = final volume
*this equation is Boyle's Law
substituting,
0.63 * 324 = P2 * 124
P2 = 0.63 * 324 / 124
P2 = 1.65 atm

hope this helps~ :)
