Practice Molar Mass in Chemistry
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The mass in grams of exactly one mole of a substance, calculated by summing the atomic masses of all atoms in the chemical formula.
How much one mole weighs. For elements, it's the number on the periodic table.
Example 1
easyCalculate the molar mass of glucose (\text{C}_6\text{H}_{12}\text{O}_6).
Example 2
mediumWhat mass of calcium chloride (\text{CaCl}_2) contains 0.75 mol? (Ca = 40.08, Cl = 35.45 g/mol)
Example 3
easyCalculate the molar mass of sulfuric acid (\text{H}_2\text{SO}_4). (H = 1.008, S = 32.07, O = 16.00)
Example 4
easyWhat mass of calcium carbonate (\text{CaCO}_3) is equal to 0.250 mol? (Ca = 40.08, C = 12.01, O = 16.00)
