turn 0 C to 273 K , 30 C to 303K then 255*85/303=101.3*V/273 V=193mL

What volume is occupied by 20. 0 g of nitrogen (N2) gas at 30 degree C. and 800 mmHg?
1 mol N2 = 28g 30C = 303K At STP, 1mol * 273K is proportional 24L * 760torr. (PV = nRT) Then we do a little bit of stoichiometry... 10g * 1mol/28g * 24L*760torr/(1mol*273K) * 303K * xL/750torr = 9.6402 L 10.0g of N2 at 30C and 750torr should occupy 9.6402L

Does density change if some of the liquid evaporates between the time the liquid is delivered to the beaker and to the time it was measured?
Whether or not the density changes if some of the liquid evaporates between the time the liquid is delivered to the beaker and the time it is measured depends on the liquid. For almost all liquids, the answer is no because there was not enough time. Water will have a density of approximately 1 and if a small amount evaporates, it will still have the same density. If you had the beaker at 100C and the room at 0C and waited until the water was 4C, it would make a difference. If the water was at 40C and the room was at 30C, it would almost make no difference. A very few substances would undergo tremendous cooling. That would bring a corresponding increase in density.

Is a 30c in bra size bigger or smaller then a 34a?
It is the same overall volume, but a different shape. A 30C will have a narrower chest that protrudes more, while a 34A has a broader chest and protrudes less. When you move down a band size, you move up a cup size to maintain the same overall volume. 34A = 32B = 30C.
