Question

Stoichiometry Practice Worksheet Solve the following stoichiometry grams-grams probierms 1) Using the following equation pioneo 2NaOH + H2SO4 2 HO . Nalso, How many grams of sodium sodium hydroxide and you have an excess of sulfuric acid? sulfate will be formed if you start with 200 grams of 2) Using the following equation: Pb(SO4)2 + 4 LiNOg Pb(NO3)4 + 2 Li2SO4 How many grams of lithium nitrate will be needed to make 250 grams of lithium sulfate, assuming that you have an adequate amount of lead (IV) sulfate to do the reaction?

Explanation / Answer

1) from equation : 2 mol NaOH = 1 mol H2SO4

NO of mol of NaOH = 200/40 = 5 mol

no of mol of Na2SO4 FROMED = 5/2 = 2.5 mol

MASS of Na2SO4 FROMED = 2.5*142 = 355 g


2) 4 mol LiNO3 = 2 mol Li2SO4

   NO of mol of Li2SO4 formed = 250/110 = 2.273 mol

   NO of mol of LiNO3 required = 2.273*4/2 = 4.546 mol

   mass of LiNO3 required = 4.546*69 = 313.674 g
