How many grams of Cl are in 465g of CaCl2

2 ways to do this

a. find %Cl in CaCl2

2 x 35.45g/mole = 70.9g Cl

70.9g Cl / 110.9g/mole CaCl2 = 63.93% Cl in CaCl2

0.6963 x 145g = 92.7g = mass Cl

b. determine moles CaCl2 present then mass Cl

145g / 110.9g/mole = 1.31moles CaCl2 present

2moles Cl / 1mole CaCl2 x 1.31moles = 2.62moles Cl

2.62moles Cl x 35.45g/mole = 92.7g Cl
