Calculate the grams of calcium present in 70 grams of calcium chloride.

37.1g of Ca

Explanation:

Hello,

Molecular formula for calcium chloride = CaCl

Molar mass = 40 + 35.5 = 75.5g/mol

Assuming there's one mole of CaCl

1 mole = mass / molar mass

Mass = 1 * 75.5

Mass = 75.5g

75.5g of CaCl contains 40g of Calcium

70g of CaCl will contain x g of Calcium

X = (70 * 40) / 75.5

X = 37.086g

Therefore, 70g of CaCl contains approximately 37.1g of Ca
