A student has conducted an experiment to prepare a salt of zinc chloride in a laboratory. The student added 10.0 g of zinc oxide powder to 50 cm of hydrochloric acid 2.0 mol dm 9. The product is then filtered and heated until dry. The student found that he obtained only 12.4 g of zinc chloride salt. Determine the mass of the zinc chloride salt that has evaporated. The following is the chemical equation for the reaction. ZnO + 2HCI ZnCl2 + H2O
[Atomic Relative Mass : Zn = 65; CI = 35.5; O = 16; H = 1]
A. 0.10 g
B. 1.20 g
C. 12.0 g
D. 13.6 g
