Question

Calculate the number of carbon atoms in 18g of glucose

Answer 1

Answer:

written below-

Explanation:

gram of glucose is equals to 1 mole of glucose

18 gram of glucose will be equal to 0.1 mole of glucose

now

one mole of glucose have 6.022 *10^ 23 number of atoms

0.1 mole of glucose will contain 0.1* 6.022* 10^ 23 mole of glucoses

now

for one molecule of glucose there are 6

carbons

Thus number of molecules of carbon in 6.022∗1022 molecules of glucose must be = 6∗(6.022∗1022)=36.132∗1022 atoms of carbon.
