80g of sugar + 80g of water = 160g of sugar water |
25g of salt + 125g of water = 150g of salt water |
5g of bicarb soda + 255g of water = 260g of bicarb soda water |
10g of coffee + 240g of water = 250g of coffee (black) |
20g of fertiliser + 480g of water = 500g of liquid fertiliser |
50g of copper sulphate + 200g of water = 250g of copper sulphate solution |
10g of bleach + 990g of water = 1 litre of diluted bleach |
