JEE Main levelNumerical answerDifficulty 2 of 3sc193

An emulsion is made from 40 mL of oil (density 0.80 g/mL) and 160 mL of water (density 1.00 g/mL). Find the mass percentage of oil in the emulsion (two decimals).

Numerical answer type, answer in %, tolerance 0.01.

Answer: 16.67 %

Mass of oil

= 40 \times 0.80 = 32.0

g and mass of water

= 160

g. Mass percentage of oil

= 32.0/192.0 \times 100 = 16.67%
