Question

Calculate the mass of sugarcan and water to prepare 250 g of 25% solution of cane sugar. Formula of cane sugar is C6H12O6.

Answer 1

25 % cane sugar solution means 25g of cane sugar in 100g of solution or 75g of water.
Since 100g of solution contains 25g of cane sugar, so 250g of solution will contain = $\frac{25}{100}\times 250=62.5g$ of cane sugar
Mass of water = 250 - 62.5 = 187.5g

Hence to prepare, 250g of 25% of cane sugar solution 62.5g of cane sugar​ and 187.5 of water is required.
