Interpretation: The mass of the solid sodium carbonate is to be determined.
Concept Introduction:
The molarity is the number of moles of the solute dissolved per liter volume of the solution. It is represented in mathematical term such that,
Where, n is the number of moles,
V is the volume of the solution.
Answer to Problem 28A
The mass of the sodium carbonate is
Explanation of Solution
Given information:
The volume of the solution,
The molarity of the solution,
The molar mass of sodium carbonate is,
Calculation:
The molarity formula is,
Firstly, find the number of moles of the sodium carbonate,
Now, use this value of number of moles in the molarity formula, and the result is,
The mass is
