3. It isn't that complicated. I gave you a formula and you are to substitute the numbers into the formula. There will always be one item in the formula not given and you solve for that.
pressure1 x volume 1 = pressure2 x volume2
pressure 1 = 483 mm
volume 1 = 10 L
pressure 2 = 762 mm
volume 2 = unknown

So 483 x 10 = 762 x v2
solve for v2.
