Question

Calculate the volume of water that needs to be added to dilute 40.0 cm3 of 0.600 mol dm−3 hcl(aq) solution to a concentration of 0.100 mol dm–3.

Answer 1

To dilute the HCl solution, you will need to add 240 cm³ of water.

Step-by-step explanation:

To calculate the volume of water that needs to be added to dilute the HCl solution, we can use the equation:

(stock concentration) × (stock volume) = (final concentration) × (final volume)

Let's solve for the unknown volume:

(0.600 mol/dm³) × (40.0 cm³) = (0.100 mol/dm³) × (unknown volume)

Dividing both sides by 0.100 mol/dm³, we find that the unknown volume is 240 cm³.
