Answer 2

0.10 moles

Step-by-step explanation:

We are given;

• Volume of the solution as 100 mL
• Molarity of glucose solution is 1.0 M

We are required to calculate the number of moles of glucose.

• We need to know that molarity of a solution is calculated by dividing the number of moles of the solute by the volume of the solution.

That is;

• Molarity = Moles of solute ÷ Volume of the solution

• Rearranging the formula;
• Moles of solute = Molarity × Volume of the solution

Therefore;

Moles of glucose = 1.0 M × 0.1 L

= 0.10 moles

Thus, the number of moles present in the solution is 0.10 moles
