What is the molar mass of a gas (96.0 g) in a 25.0 L container at 27.0 °C? The pressure inside the container is 3.04E5 Pa.

Answer 1

PV=nRT
n=96/molmass * PV/RT

solve for molmass

Answer 2

Silver has a density of 10.5 g/cm3 and crystallizes in a face-centered cubic unit cell (see below). Calculate the atomic radius (in Å) of Silver.
