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

Options

A. `7.92xx10^(25)` atoms
B. `6xx10^(23)` atoms
C. `6.022xx10^(25)` atoms
D. 1000 atoms

Answer

A

Explanation

One molecule of sugar `(C_12H_22O_11) ` = 45 atoms
Number of moles of sugar `=(1000)/(342) =2.92`
Number of molecules `= 2.92 xx6.023 xx10^(23)`
`= 17.60 xx10^(23)` molecules
Number of atoms `=45 xx17.60 xx10^(23)`
`=7.92 xx10^(25)` atoms
