a.
Number of moles = Mass in gram / Atomic weight
Atomic weight of Sn = 118.71 g/mol
Number of moles of Sn = 10.00 g / 118.71 g/mol = 0.0842 mol
From reaction, 1.0 mol of Sn produces 1.0 mol of SnF2 then 0.0842 mol of Sn will produce 0.0842 mol of SnF2.
Molar mass of SnF2 = 156.707 g/mol
Mass of SnF2 can be produced = 156.707 g/mol * 0.0842 mol = 13.2 g
b.
Percent yield = Actual yield * 100 / Theoretical yield
Percent yield = 11.00 g * 100 / 13.2 g = 83.33%
Percent yield = 83.33%
