A 3.65 g sample of an unknown gas at 75°C and 1.05 atm is stored in a 2.15 L flask. What is the density of the gas? What is the molar mass of the gas?

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
