How many atoms in total are present in 1kg of sugar?

A

`7.92xx10^25` atoms

B

`6xx10^23` atoms

C

`6.022xx10^25` atoms

D

1000 atoms

Text Solution

Verified by Experts

One molecule of sugar `(C_12H_22O_11)` = 45 atoms
No. of moles of sugar `=1000/342=2.92`
No. of molecules `=2.92xx6.0223xx10^23`
No. of atoms `=45xx17.60xx10^23`
`=7.92xx10^25` atoms
