By definition, one mole would be the same as the molecular mass. You take the number of moles and multiply it by the molecular mass. So if you have just 1 mole, the number of grams will be the added atomic masses of the elements in the compound.
Ca- 40.08
Cl- 35.5
CaCl- 75.6 grams
To determine the number of moles in 18.4g of CaCl2, first calculate the molar mass of CaCl2 (40.08 + 2*35.45 = 110.98 g/mol). Then, divide the given mass by the molar mass to find the number of moles. In this case, 18.4g / 110.98 g/mol = 0.165 moles of CaCl2.
