Use stoichiometry (Ch 13) to calculate how many grams of PbSO4(s) would be produced if 5.50 grams of LiNO3 were produced. It will be helpful to do this on paper first. Li2SO4(aq) + Pb(NO3)2(aq) ⟶2 LiNO3(aq) + PbSO4(s) a. Select the value for the molar mass of LiNO3, with the correct value, significant figures, and units. b. Select the value for the molar mass of PbSO4, with the correct value, significant figures, and units. c. Select the mole ratio that will be used, with the correct values and units. d. Select the first operation and conversion factor used to cancel the given unit and substance. e. Lastly, select the calculated answer, expressed with the appropriate significant figures and unit.

The balanced reaction taking place is given as, => Li2SO4 (aq) + Pb(NO3)2 (aq) → 2 LiNO3 (aq) + PbSO4 (s) Given: Mass of LiNO3 produced = 5.50 g. a) Molar mass of LiNO3 = Atomic mass of Li + Atomic mass of N + Atomic mass of O × 3=> Molar mass of LiNO3 = 6.93 + 14 + 16 × 3 = 68.93 g/mol. b) Molar mass of PbSO4 = Atomic mass of Pb + Atomic mass of S + Atomic mass of O × 4=> Molar mass of PbSO4 = 207.2 + 32 + 16 × 4 = 303.2 g/mol. c) From the above-balanced reaction, we can see that 2 moles of LiNO3 is produced with 1 mole of PbSO4. Hence the moles of PbSO4 produced = moles of LiNO3 produced2=> Mole ratio = 1 mole PbSO42 mol LiNO3 d) substituting the values into the equation of part c we get, => Moles of PbSO4 produced = 5.50 g LiNO3 × 1 mol LiNO368.93 g LiNO3 × 1 mol PbSO42 mol LiNO3 = 0.03989555 mol approx. e) The mass of PbSO4 produced = moles × molar mass = 0.03989555 mol PbSO4 × 303.2 g PbSO41 mol PbSO4 = 12.1 g approx. Hence the answer is 12.1 g approx.

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "elem…
