Mass of sucrose= 225 g
Mass of water= 225 g
Mass in grams of sucrose and the mass in grams of water that must be used to prepare 450g of 50% by mass of sucrose solution can be calculated as:
"Mass percentage = Mass of solute / Mass of solution × 100"
Here, Mass percentage = 50 %
Mass of solution = 450 g
Mass of solute = ?
→ 50 = Mass of sucrose / 450 g × 100
Cross multiplying:
∴ Mass of sucrose = 50 × 450 ÷ 100
= 225 g
Mass of water = Mass of solution - Mass of sucrose
= 450 g - 225 g
= 225 g
