Question

10ml , 30ml, and 60ml of three liquids are mixed together.
What is the concentration in volume percent of the solutes?

Answer 1

total amount if liquids is 100ml
concentration of volume is 0.33%

Answer 2

Answer: The concentration of solute 1 is 0.1% v/v, solute 2 is 0.3% v/v and solute 3 is 60%v/v.

Explanation:

To calculate the percentage in volume percent, we divide the volume of solute by the volume of solution.

Volume of solution = Volume of Solute 1 + Volume of Solute 2 + Volume of Solute 3

Volume of solution = (10 + 30 + 60)mL = 100mL

Concentration of Solute 1 in volume percent will be = $\frac{\text{Volume of solute 1}}{\text{Volume of solution}}=\frac{10mL}{100mL}=0.1$

Concentration of Solute 2 in volume percent will be = $\frac{\text{Volume of solute 2}}{\text{Volume of solution}}=\frac{30mL}{100mL}=0.3$

Concentration of Solute 3 in volume percent will be = $\frac{\text{Volume of solute 3}}{\text{Volume of solution}}=\frac{60mL}{100mL}=0.6$

Hence, the concentration of solute 1 is 0.1% v/v, solute 2 is 0.3% v/v and solute 3 is 60%v/v.
