1. 2H_2O+Na_2SO_4, how many grams of sodium sulfate will be formed if ...
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)
