19. For the reaction HCl + NaOH → NaCl + H2O, how many moles of hydrochloric acid are required to
produce 150. g of water?
a. 12.2 mol
b. 4.16 mol
c. 8.32 mol
d. 1.50 mol
the molecular mass of water is about 18.02, to get the moles of water 150/18.02=8.32 mol, since the coefficients of HCl and H2O are the same, the number of moles would be the same as well
