Answer :
3.4 mol HCl * ( 36.46 g / 1 mol ) = 123.964 g HCl = 1.2 x 10^2 g HCl
Convert moles of HCl to grams of HCl using the molar mass ( 36.46 g/mol ).
Revise your answer to have the right number of significant figures ( 2 significant figures in this case, as determined by the the number of figures in the value with the least figures).
