(a)
Interpretation: The mass in grams of 0.250 mol of sucrose needs to be calculated.
Concept Introduction: Mass of a substance can be calculated from the number of moles and molar mass as follows:
Here, n is the number of moles and M is the molar mass.
(a)
Explanation of Solution
The given substance is 0.250 mol of sucrose. Here, the molar mass of sucrose is 342.3 g/mol thus, mass can be calculated as follows:
Substitute the values,
Thus, the mass of 0.250 mol of sucrose is
(b)
Interpretation: The mass in grams of 0.250 mol of sodium chloride needs to be calculated.
Concept Introduction: Mass of a substance can be calculated from the number of moles and molar mass as follows:
Here, n is the number of moles and M is the molar mass.
(b)
Explanation of Solution
The given substance is 0.250 mol of sodium chloride. Here, the molar mass of sodium chloride is 58.44 g/mol thus, mass can be calculated as follows:
Substitute the values,
Thus, the mass of 0.250 mol of sodium chloride is 14.61 g.
(c)
Interpretation: The mass in grams of 0.250 mol of potassium permanganate needs to be calculated.
Concept Introduction: Mass of a substance can be calculated from the number of moles and molar mass as follows:
Here, n is the number of moles and M is the molar mass.
(c)
Explanation of Solution
The given substance is 0.250 mol of potassium permanganate. Here, the molar mass of potassium permanganate is 158.034 g/mol thus, mass can be calculated as follows:
Substitute the values,
Thus, the mass of 0.250 mol of potassium permanganate is 39.5 g.
