Answer 2

Concept introduction:

One mole of any substance have same number of molecules that is Avogadro number of molecules $6.022*10^{23}$.

Explanation:

Given that, $180g$ of glucose and $342g$ of sucrose.

We have to find, number of atoms and molecules.

According to the question,

Molar mass of glucose = $180g$

∴ Number of moles of glucose is $180/180=1 mole$.

Number of atoms in one mole of sucrose are $C6H12O6$=$6+12+6=24$.

Molar mass of sucrose = $342g$

∴ Number of moles of sucrose is $342/342=1 mole$.

Number of atoms in one mole of sucrose are $C12H22O11$=$12+22+11=45$.

Final Answer:

$180g$ of glucose and $342g$ of sucrose has same number of molecules but different number of atoms present in them.
