Question

Zinc reacts with dilute hydrochloric acid according to the equation:
Zn(s) + 2HCl (aq) → ZnCl2 (aq) + H2 (g)
In the experiment, a 1.046 g sample of an alloy containing zinc reacted with 120.0 mL of 0.200 M HCl solution.
(a) Calculate the amount (in mol) of hydrochloric acid that reacted in the experiment.
