Question

calculate the number of C,H and O atoms in 36 gram of glucose ?​

Answer 1

Glucose is C6H12O6, making its molar mass near 180.

Moles =mass/mr = 36/180 =0.2

One mole of glucose would have 6x Avogadro's number of C atoms

0.2 moles of glucose would have 1.2 x Avogadro's number of C atoms

= 1.2 x ( 6 x 10^23 ) = 7.2 x 10 ^23

Hope it helps you ☺️
