Answer:
677.39 g/mol
Explanation:
Step 1: Find molar masses of elements
Carbon (C) - 12.01 g/mol
Hydrogen (H) - 1.01 g/mol
Oxygen (O) - 16.00 g/mol
Step 2: Multiply the amount present
12.01 g/mol · 46 = 552.46 g/mol
1.01 g/mol · 92 = 92.92 g/mol
16.00 g/mol · 2 = 32.00 g/mol
Step 3: Add up all the molar masses to find compound molar mass
552.46 g/mol + 92.92 g/mol + 32.00 g/mol = 677.39 g/mol
