Hi, could anyone help me with this question?
It's from a past paper and driving me mad...
1. The level of hypochlorite in swimming pools needs to be maintained between 1 and 3 parts per million (1 – 3 ppm).
400 cm3 of a commercial hypochlorite solution will raise the hypochlorite level of 45 000 litres of water by 1 ppm. Calculate the volume of hypochlorite solution that will need to be added to an Olympic-sized swimming pool, capacity 2, 500, 000 litres, to raise the hypochlorite level from 1 ppm to 3 ppm.
