Question

A gas bubble with a volume of 1.0 mL originates at the bottom of a lake where the pressure is 3.00 atm. Calculate its volume when the bubble reaches the surface of the lake where the pressure is 695 torr , assuming that the temp doesn't change.
I got 0.003 L, is that correct

Answer 1

Your answer is ok unless you want to be picky about the number of significant figures. You are allowed 2 (from the 2 in 1.0 mL). I get 3.28 mL which would round to 3.3 mL or 0.0033 L.
