Question

15 g of methyl alcohol is present in 100 ml of solution if the density of methyl alcohol in solution is 0.96 g/ ml calculate the mass percentage of methyl alcohol in solution

Answer 1

hope this helps you ☺

Answer 2

Answer: The mass percentage of methyl alcohol in solution 15.62 %

Explanation:

Mass of methyl alcohol present = 15 g

Volume of solution: 100 mL

Density of solution = 0.96 g/mL

${Density}= \frac{Mass}{Volume}$

Mass of the solution =  (Density of the solution)(Volume of the solution)

$=(0.96 g/mL)\times (100 mL)=96 g$

Mass percentage of methyl alcohol in solution:

$\text{mass percentage of methyl alcohol}=\frac{15}{96}\times 100=15.62\%$

The mass percentage of methyl alcohol in solution 15.62 %
