Answer:
The Percent composition of isopropanol in the mixture is 29.07 %
Explanation:
Step 1: Data given
Number of moles isopropanol (C3H8O) = 2.52 moles
Mass of the solution = 521 grams
Molar mass of isopropanol (C3H8O) = 60.1 g/mol
Step 2: Calculate mass of isopropanol
Mass isopropanol = moles isopropanol * molar mass isopropanol
Mass isopropanol = 2.52 moles * 60.1 g/mol
Mass isopropanol = 151.45 grams
Step 3: Calculate the percent composition of isopropanol in the mixture
Percent composition of isopropanol = (mass isopropanol / total mass of mixture) * 100 %
Percent composition of isopropanol = (151.45 grams / 521 grams ) * 100 %
Percent composition of isopropanol = 29.07 %
The Percent composition of isopropanol in the mixture is 29.07 %
