Answer:

# 329 \ g \ Cl#

Explanation:

Molar atomic masses
Ca= 40.08 ; Cl= 35.45

Molar mass of #CaCl_2#
#MM_(CaCl_2)= 40.08 + 2×35.45 = 110.98 \ g.mol^-1#

#515\ g\ CaCl_2xx (1 \ mol.\ CaCl_2)/ (110.98 \ g \ CaCl_2) xx (2 \ mol. \Cl)/ (1\ mol.\ CaCl_2)xx (35.45 \ g \ Cl)/ (1 \ mol. \ Cl)#

#=329 \ g \ Cl#
