Question

Hydrogen chloride gas can be prepared by the following reaction:
2NaCl(s) + H2SO4(aq) --> 2HCl(g) + Na2SO4(s)
How many grams of HCl can be prepared from 2.00 mol H2SO4 and 2.56 mol NaCl?

Answer 1

First You need to find out limited regents
here limiting regents is 2.56 mol NaCl
so 2.56g NaCl * 1 mol NaCl/ 58.49 NaCl*2 mol HCl/ 2 mol NaCl* 36.46 g HCl/ 1 mol HCl = 93.50 g
