Answer:
Molarity of sucrose = 0.116 M (Approx.)
Explanation:
Given:
Volume of solution = 0.5 liter
Mass of sucrose in gram = 20 gram
Molar mass of sucrose 342.3 g/mol
Find:
Molarity of sucrose
Computation:
Mole of sucrose = Mass of sucrose in gram / Molar mass of sucrose
Mole of sucrose = 20 / 342.3
Mole of sucrose = 0.058 (Approx.)
Molarity of sucrose = Mole of sucrose / Volume of solution
Molarity of sucrose = 0.058 / 0.5
Molarity of sucrose = 0.116 M (Approx.)
