What volume of a 0.4M solution can be prepared with 4.6 moles of
sucrose? *
How ?

11.5 L

Explanation:

Sucrose is a dissacharide with a chemical formula C12H22O11. It is composed of glucose and fructose.

Given that:

volume of sucrose = ?

Concentration of sucrose = 0.4M

(Note that molarity is the same as concentration in moles per litres,

So, 0.4M = 0.4 mol/L)

Amount of moles of sucrose = 4.6 moles

Recall that the concentration of a solution depends on the amount of solute dissolved in a particular volume of solvent.

I.e Concentration in mol/L =

Amount in moles / Volume in liters

0.4M = 4.6 moles / Volume

Volume = 4.6 moles / 0.4 mol/L

Volume = 11.5 L

Thus, 11.5 liters of 0.4M solution can be prepared with 4.6 moles of sucrose.
