Answer:

0.102 M

Explanation:

Given data

  • Mass of sucrose (solute): 35.0 g
  • Volume of solution: 1.000 L

Step 1: Calculate the moles of solute

The molar mass of sucrose is 342.3 g/mol. The moles corresponding to 35.0 g of sucrose are:

[tex]35.0g \times \frac{1mol}{342.3g} =0.102mol[/tex]

Step 2: Calculate the molarity of sucrose in the solution

The molarity is equal to the moles of solute divided by the liters of solution.

[tex]M=\frac{0.102mol}{1.000L} =0.102 M[/tex]
