How do you find the molar mass of a gas?
The molar mass is determined by applying the Ideal Gas Law, PV = nRT, where P is the pressure (in atm), V is the volume (in L), n is the number of moles of gas, R is the universal gas constant (0.08206 L∙atm/mol∙K), and T is the temperature (in K).
What type of bond is Br2?
Having the same electronegativity of both atoms, both share an equal proportion of charge. The atoms forming a covalent bond having equal electronegativity are nonpolar in nature. Therefore, the Br2 molecule is a nonpolar molecule.

How do I calculate molecular mass?
Find the atomic mass for each element using the mass shown in the Periodic Table or Atomic Weight Table. Multiply the subscript (number of atoms) times that element's atomic mass and add the masses of all the elements in the molecule to obtain the molecular mass.
How do you calculate moles of gas?
Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.
