Question

how many mole of carbon are present in 60gm of glucose​

Answer 1

1 molecule of glucose contains 6 atoms of C, 12 atoms of H, and 6 atoms of O • 1 mole of glucose contains 6 moles of C atoms, 12 moles of H atoms, and 6 moles of O atoms. 10 moles of glucose contains 60 moles of C, 120 moles of H, and 60 moles of O atoms.

Answer 2

Given:

Mass of glucose = 60 gm

To Find:

Number of moles of carbon in 60 gm of glucose.

Solution:

We can solve the problem by the following method.

We know that molecular mass of glucose is

180.156 gm

Now, as formula of glucose C6H12O6 suggests,

one molecule of glucose has 6 moles of carbon, 12 moles of hydrogen and 6 moles of oxygen.

Hence,

180.156 gm contains 6 moles of carbon.

Then,

60gm contains- ?

On cross-multiplication,

60 gm contains 1.99 moles or 2 moles of carbon.

Hence, there are 2 moles of carbon in 60 gm of glucose.
