Use equation n=PV/RT where n is number of moles and R is gas constant. Use R= .8314 L-Atm/mol-K. convert 3 ml to liters(3/1000) and 100C to Kelvin (100+273) and solve for moles.
Convert moles to grams. 1 mol of N2 equals 28 grams

grams law of diffusion deals with gases spreading out to occupy the shape of their container.
Well, since a gas spreads to encompass its container, it should have the same volume as its container.
Whilst I'm not going to do the actual calculation for you, I suggest you use the ideal gas law. PV=nRT P is Pressure in pascals (1 ATM is roughly 100,000pa) V is Volume in cubic metres (be careful converting mL to cubic metres) n is the number of mols R is the molar gas constant which is roughly 8.31 T is temperature in kelvin so to find mass you rearrange for number of mols n=PV/RT Work it out and then use the molar mass of nitrogen to convert into grams
The answer will be the sum of the Flask A and Flask B. The Reason: A gas occupies all the space within a container.
The gas expand to occupy the volume of the container.
Placing a rock in a container does not alter the volume of the container, although it does occupy some of that volume.
Liquids adopt the shape of the part of the container that they occupy. Gases adopt the entire shape and volume of their container.

Gases do not have a fixed shape or volume; they expand to completely fill the container they occupy.

Well, since a gas spreads to encompass its container, it should have the same volume as its container.
Because when it is cooled, the air inside contracts, or shrinks, so to avoid creating a void the container will crush inward to occupy the space.
-- Some of the air in the container is forced out, being displaced by the volume of the ruler, and being unable to occupy that same space at the same time. If there is liquid in the container, then the same goes for the liquid. -- If there is liquid in the container, then at least part of the ruler becomes wet.
