Canvas Classes · Accepted Answer

Strategy:
 First, determine the molar mass of the compound using the mass percentage of Carbon and the fact that each molecule contains exactly two Carbon atoms. Then, divide the given sample mass by the molar mass to find the moles.

Step 1: Calculate Molar Mass (M)
1 mole of compound has 2 moles of Carbon .
Given Carbon is  of total mass:

Step 2: Calculate Moles in 10 g
