Interpretation:The mass of solute in grams that are dissolved in given sample needs to be calculated.
Concept Introduction:The molar concentration of a solute in a solution can be expressed in terms of molarity as moles of solute present in per liter of solution. Mathematically,
Answer to Problem 9RE
The mass of solute is
Explanation of Solution
Given:
500.0 mL sample of 0.50 M sodium sulfate.
Converting the given volume of sample from mL to L as:
The formula to calculate number of moles is:
Now, equation (1) an be rewritten as:
The molar mass of sodium sulfate is
Substituting the given values in equation (2) to determine the mass of solute as:
Hence, the mass of solute is
