What is the mass percentage of carbon in 5.000 g of sucrose

Answer : The mass percentage of carbon in sucrose  is, 42.1 %

Explanation: Given,

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

Molar mass of O = 16 g/mole

First we have to calculate the molar mass of sucrose.

Molar mass of sucrose =

Now we have to calculate the mass of carbon in 5 g of sucrose.

As we now that there are 12 number of carbon atoms, 22 number of hydrogen atoms and 11 number of oxygen atoms.

The mass of carbon =

As, 342 g of sucrose contains 144 g of carbon

So, 5 g of sucrose contains of carbon

Now we have to calculate the mass percentage of carbon in sucrose.

Formula used :

Now put all the given values in this formula, we get:

Therefore, the mass percentage of carbon in sucrose  is, 42.1 %

the answer is a
