What is the molar mass (in g/mol) of ? (H = 1, C = 12, N = 14, O = 16, Na = 23, S = 32, Ca = 40)
Answer and explanation
Correct answer: D. 100
- Step 1: Identify the constituent elements and their atom counts from the formula : it consists of one calcium atom, one carbon atom, and three oxygen atoms.
- Step 2: Sum the respective relative atomic masses: .
- Step 3: The calculated molar mass of the compound is .
