Asked by Cynthia
Zn metal was allowed to react with hydrochloric acid to produce hyrdogen gas.This gave a total of 555mL of gas collected over water at 20C and a pressure of 747mm of Hg. How many moles of hydrogen were collected? The vapor pressure of water at 20C is 18mm Hg.

PV = nRT
P = (747-18/760) = ?atm
V = 555 mL = 0.555L
R = you know it
T = 20C = 273K
Solve for n.
