When potassium cyanide (KCN) reacts with hydrochloric acid, hydrogen cyanide (HCN), a poisonous gas, is produced. The equation is
Calculate the number of g of KCN that will react with 5.74 mol of HCl.

Nasty gases ....
KCN(aq) + HCl(aq) --> HCN(g) + KCl(aq)
..? g .......... 5.74 mol
5.74 mol HCl x (1 mol KCN / 1 mol HCl) x (65.12g KCN / 1 mol KCN) = 374g KCN
