Answer:
90.71%
Explanation:
From the equation of reaction:
1 mole of salicylic acid requires 1 mole of methanol in order to produce 1 mole of methyl salicylate.
<em>mole = mass/molar mass</em>
1.6 g of salicylic acid = 1.6/138.121 = 0.012 moles
15 g of methanol = 15/32.04 = 0.47 moles
<em>Salicylic acid is the limiting reagent and hence, 0.012 moles of methyl salicylate would be produced according to the mole ratio above.</em>
0.012 moles of methyl salicylate = 0.012 x 152.1494 = 1.83 g
The theoretical yield of methyl salicylate is 1.83 g while the actual yield is 1.66 g.
<em>Percentage yield = actual yield/theoretical yield x 100%</em>
1.66/1.83 x 100% = 90.71%
