Step 1

The amount of glucose can be calculated by multiplying the volume of the solution by the molarity of the solution. In this case, the volume is $150.0 \mathrm{~mL}$ and the molarity is $0.1 M$. So, the amount of glucose is $150.0 \mathrm{~mL} \times 0.1 M = 15.0 Show more…

Key Concepts

Dilution

Dilution is the process of adding solvent to a solution to decrease the concentration of the solute. The key principle of dilution is that the number of moles of solute remains constant while the volume increases, leading to a proportional decrease in molarity.

Conservation of Moles

In any dilution process, the total number of moles of solute remains unchanged. This concept, which ensures that the solute mass is conserved, allows one to calculate the new concentration after dilution by dividing the unchanged number of moles by the new total volume.

Molarity

Molarity is the number of moles of solute per liter of solution. It is a fundamental concentration measure that allows chemists to quantify the amount of a substance in a given volume of solution, facilitating calculations and comparisons between different solutions.
