The mass ratios are divided by the molar masses of respective molecules to obtain the mole ratio, which is then simplified to give the final mole ratio； The molar ratios are multiplied by the molar masses of respective molecules to obtain the mass ratio, which is then simplified to give the final mass ratio.
n1/n2=(m1/M1)/(m2/M2) where n1 is the number of moles of substance 1, n2 is the number of moles of substance 2, m1 is the mass of substance 1, M1 is the molar mass of substance 1, m2 is the mass of substance 2, and M2 is the molar mass of substance 2. That’s the formula; you can derive it yourself if needed
