1 litre of the diluted solution must contain 10g of H2S04 5L of the diluted solution must contain 50g of H2S04 the concentration of the acid = 95%
> 95g of H2S04 is present in 100g of the acidic solution
> 50g of H2S04 will be present = 50 * 100 / 95
= 52.64g
> 95g of H2S04 is present in 100g of the acidic solution
> 50g of H2S04 will be present = 50 * 100 / 95
= 52.64g
