Question

Calculate the concentration of CO2 in water, which contains 20.25mL of CO2 per 675mL of solution? ​

Answer 1

To calculate the concentration of CO2 in water, we need to use the formula:

Concentration = (Volume of Solute / Volume of Solution) x 100%

We are given that the volume of CO2 in water is 20.25 mL and the volume of the solution is 675 mL. Therefore, we can substitute these values into the formula and get:

Concentration = (20.25 mL / 675 mL) x 100%

Concentration = 0.03 x 100%

Concentration = 3%

Therefore, the concentration of CO2 in water is 3%.
