Answer;
68.46 g of sucrose in 100mL
Solution and explanation;
Given 2L of 2 mol/L sucrose solution
Moles = concentration x volume
Therefore; The number of moles in this solution is 2 L x 2 mol/L = 4 mol
The molecular mass of sucrose is 342.3 g/mol.
Mass = Moles × Molecular weight
Therefore the mass of sucrose in 2 L;
= 4 mol x 342.3 g/mol = 1369.2g
but; 2L/20 = 100 mL
= 1369.2/20 = 68.46
Hence; you would have 68.46 g in 100 mL
