Calculate the mass of methyl formate, which can be obtained from formic acid and 3.2 g of methyl alcohol, if the yield of the reaction product is 80%
Let us write down the equation for obtaining methyl formate.
HCOOH + CH3OH = CHOOCH3 + H2O.
Let’s calculate the number of moles of substances for methanol.
n (CH3OH) = m / Mr = 3.2 / 32 = 0.1 mol.
Theoretical weight of methyl formate:
m (ether) = n • Mr = 0.1 • 60 = 6 g.
True mass based on product yield.
m (ether) = m theor. • W practical. / W theor. = 6 * 80/100 = 4.8 g.
