A chemist wishes to determine the rate of reaction of zinc with hydrochloric acid. The equation for the reaction is:

Zn(s) + 2HCl(aq) ---> H2(g) + ZnCl2(aq)

A piece of zinc is dropped into 1.00 L of 0.100 M HCl and the following data were obtained:
Time/Mass of Zinc
0 s/0.016 g
4 s/0.014 g
8 s/0.012 g
12 s/0.010 g
16 s/0.008 g
20 s/0.006 g

If the rate of consumption of magnesium is 5.0 x 10-9 mol/s, find the rate of
consumption of HCl in moles/s.

oops sorry i meant if the rate of comsumption of ZINC is 5.0 x 10^-9 mol/s...
