Answer 2

Given - 10% by volume of pure orange extract

Find - (a) What volume (in mL) of pure orange extract is present in 100 mL of the drink? (b) What volume (in mL) of water is present in the drink?

Solution - Volume by volume composition represents volume of solute/volume of solution*100

In the question, solute is pure orange extract and solvent is water.

Hence, pure orange extract is 10 mililitres.

Water present in juice is volume of solvent = volume of solution - volume of solute

Volume of water = 100 - 10

Volume of water = 90 mililitres.

Hence, volume of pure orange extract (a) is 10 ml and volume of water (b) is 90 ml
