Question

the molar mass of calcium chloride (cacl2) represents the mass of one mole of: A) CaCl2 molecules B) calcium ions and chlorine molecules C) CaCl2 formula units or D) CaCl formula units

Answer 1

A) CaCl₂ molecules

The molar mass of any substance is the mass of one mole of that substance, and one mole of any substance contains 6.02 x 10²³ particles. The molar mass of any substance may be computed by summing the atomic masses of the atoms present in the molecule. The molar mass for calcium chloride is 110.98 grams.
