Question

How many moles of carban are present in 60g of glucose?

Answer 1

Answer:

hi

Explanation:

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

Answer:

The number of moles of carbon present in $60g$ of glucose is $2 moles$.

Explanation:

Given,

The mass of glucose = $60g$

The number of moles of carbon present in $60g$ of glucose =?

As we know,

• The formula for glucose is $C_{6} H_{12} O_{6}$.

From this, we can say that one mole of glucose contains 6 moles of carbon.

Now, as we know,

• The molar mass of $C_{6} H_{12} O_{6}$ = $180g/mol$

Therefore,

• The number of moles of glucose = $\frac{Given mass}{Molar mass}$ = $\frac{60}{180}$ = $\frac{1}{3} mol$

Now,

• $1 mole$ of glucose = $6 mole$ of carbon
• $\frac{1}{3} mole$ of glucose = $6\times \frac{1}{3}$ = $2 moles$ of carbon

Hence, the number of moles of carbon present in $60g$ of glucose = $2 moles$
