cannot equate weight and volume without the density of liquid or the concentration
No, 45g is not equal to 50mL. Grams and milliliters are different units of measurement. Grams measure mass or weight, while milliliters measure volume. To determine if 45g is equal to 50mL, you would need to know the density of the substance being measured.
Ratio water : plaster = 45 ml : 100 g You need to find how many lots of 100g are in 250 g and that tells you how many lots of 45 ml you need: lots required = 250g / 100g → need 45 ml × 250g / 100g = 45 ml × 2.5 = 112.5 ml of water.
