Number of atoms in 558.5 g Fe (molar mass Fe= `55.85 g mol^(-1)`)

twice than in 60 g carbon

`6.023 xx 10^(22)`

half that of 8g He

`558.6 xx 6.023 xx 10^(23)`

Verified by Experts

The correct Answer is:

558.5 g Fe = 10 moles
`=10 xx 6.023 xx 10^(23)`atoms.
60 g C = 5 moles `=5 xx 6.023 xx 10^(23)` atoms.
