Here, n is number of atoms.
Answer to Problem 7STP
Correct Answer: Option B. 42.10%.
Explanation of Solution
The given compound is sucrose with formula
The molar mass of C, H and O is 12.01 g/mol, 1.008 g/mol and 15.999 g/mol respectively.
Thus, molar mass of compound will be:
Now, the mass percent of carbon can be calculated as follows:
Thus, the mass percent of carbon in table sugar is
Thus, the correct option is B that is 42.10%.
