(b) Answer the question.


Expert Answer

Step 1

For determining the mass of solute in 0.500 L of 0.30 M glucose.

  1. Calculate the number of moles of glucose present in 0.500 L of solution.
  2. Calculate the molar mass of glucose.
  3. Calculate the mass of glucose (solute) using the moles of glucose and molar mass of glucose.
Step 2

Molarity is defined as the number of moles present in 1 L of the solution. Using the relation between molarity and moles, the number of moles is calculated as follows:
