Ask AI: How much water should I add to a 50% solution to dilute it to 10%?

To find out how much water you should add to dilute a 50% solution to 10%, you can use the dilution formula: C1 × V1 = C2 × V2 Where: C1 = Initial concentration (50%) V1 = Initial volume C2 = Final concentration (10%) V2 = Final volume Assuming that you have 1 liter (1000 ml) of the 50% solution: 0.50 × 1000 ml = 0.10 × V2 500 = 0.10 × V2 V2 = 500 / 0.10 V2 = 5000 ml Now, subtract the initial volume (V1) from the final volume (V2) to find the amount of water to be added: Water to be added = V2 - V1 Water to be added = 5000 ml - 1000 ml Water to be added = 4000 ml So, you will need to add 4000 ml (4 liters) of water to the original 1-liter 50% solution to dilute it to a 10% concentration.
