Question

How many grams of HCl are produced when 15.2 mol H2O react?

Answer 1

perhaps write the balanced equation to sus the stoichiometry

Answer 2

HCl(g) + H2O(l) --> H3O+Cl-(aq) ( we see the molar ration governing HCL and H2O are 1:1

so number of moles of h20=number of moles of hcl

Answer 3

n(hcl)=m/M
m(hcl)=n*M
m(hcl)=15.2*Molar mass

find the molar mass and then multiply it with the number of moles( 15.2Moles) to find the mass of hcl in grams
