We know from the formula of Cr₂Cl₃, that each mole of the compound consists of 2 moles of Cr. Thus,
moles of Cr = moles of Cr₂Cl₃ x 2
= 0.3155 x 2

= 0.631 mole of Cr

Determine the number of moles of Cr atoms in 50.00grams of Cr2Cl3 molar mass of Cr2Cl3 = 158.5 g/mole number of mole of Cr2Cl3 in 50 grams of Cr2Cl3= 0.3155 moles
