• Use the mole analogy of the reactant with the product. and substitute with the mole definition. Answer is 355 grams. Explanation:.

• Use the mole analogy of the reactant with the product. and substitute with the mole definition. Answer is 355 grams. Given the molecular weights: Mr_(NaOH)=40 g/(mol) Mr_(Na_2SO_4)=142 g/(mol) The analogy of the moles will be held constant: n_(NaOH)/n_(Na_2SO_4)=2/1 n_(NaOH)/n_(Na_2SO_4)=2 For each one, substitute: n=m/(Mr) Therefore: n_(NaOH)/n_(Na_2SO_4)=2 (m_(NaOH)/(Mr_(NaOH)))/(m_(Na_2SO_4)/(Mr_(Na_2SO_4)))=2 (200/40)/(x/142)=2 (200*142)/(40x)=2 200*142=2*40x x=(200*142)/(2*40)=(100*142)/40=10*142/4=1420/4= =710/2=355grams (or just use a calculator) ## 3.
