Answer:

Explanation:

First we find the Molecular weight of CaCl2

looking at the periodic table the MW of Ca is 40.078 and Cl is 35.453 and the ratio of ca to cl is 1:2 so we multiply cl by 2 which is 35.453*2=70.906

we add them together: 40.078 + 70.906 = 110.984 g/mol

now:

[tex]\frac{110.984 grams}{mol}[/tex] * 3.45 mol

the mol cancels out and we left with 3.45 * 110.984 grams = 382.89 grams
