Question

Calculate the formula mass of each compound. Keep at least one decimal place in atomic masses from the periodic table.MgCl2

Answer 1

From the periodic table:

Mg = 24.305 amu

Cl = 35.453 amu x 2 since there are 2 Cl in MgCl₂ = 70.906

TOTAL = 24.305 + 70.906 = 95.211 g/formula unit (to at least 1 decimal place)
