Answer:
Percent yield of SiC is 77.0%.
Explanation:
Balanced reaction:
Molar mass of SiC = 40.11 g/mol
Molar mass of = 60.08 g/mol
So, 100.0 kg of =
moles of
= 1664 moles of
According to balanced equation, 1 mol of produces 1 mol of SiC
Therefore, 1664 moles of produce 1664 moles of SiC
Mass of 1664 moles of SiC = = 66743g = 66.74 kg (4 sig. fig.)
Percent yield of SiC = [(actual yield of SiC)/(theoretical yield of SiC)]%
= %
= 77.0%
