m solution (sugar) = 600 g
ω (sugar) = 20%
m (sugar) -?
m (H2O) -?
1) Calculate the mass of sugar in the solution, which will need to be taken to prepare the solution:
m (sugar) = ω (sugar) * m solution (sugar) / 100% = 20% * 600/100% = 120 g;
2) Calculate the mass of water that will be needed to prepare the solution:
m (H2O) = m solution (sugar) – m (sugar) = 600 – 120 = 480 g.
Answer: The mass of sugar is 120 g; water – 480 g.
