WebJul 1, 2024 · Avogadro's Law shows that volume or pressure is directly proportional to the number of moles of gas. Putting these together leaves us with the following equation: P1 × V1 T1 × n1 = P2 × V2 T2 × n2 As with the other gas laws, we can also say that (P × V) (T × n) is equal to a constant. WebAug 24, 2024 · The formula to calculate the moles from grams is: n = \frac {m} {m_ {\text {mol}}} n = mmolm Where we can identify: n n — The number of moles, both of molecules and atoms; m m — The mass of the substance, in grams; and m_ {\text {mol}} mmol — The molar mass of the substance, in \text {g}/\text {mol} g/mol.
