Answer is: the maximum mass of sugar that could be dissolved in 1.3 l of water in room temperature is 2652 grams. The solubility of sugar in water in room temperature is 204 g/100 ml. Make proportion, if 204 grams of sugar dissolve in 100 ml of water, than how much dissolve in 1300 ml of water: 204 g : 100 ml = m(sugar) : 1300 ml. m(sugar) = 204 g · 1300 ml ÷ 100 ml. m(sugar) = 2652 g ÷ 1000 g/kg = 2,652 kg.
