A sample of vitamin C is known to contain `2.58 xx 10^(24)` oxygen atoms. How many molesof oxygen atoms are present in the sample?

Text Solution

Verified by Experts

One mole of oxygen atoms=`60022xx10^(23)(N_(A))`
`6.022xx10^(23)"atoms of oxygen"=1"mol"`
`2.48 xx10^(25)"atoms of oxygen"=(1"mol")xx((2.48xx10^(25)))/(6.022xx10^(23))=41.18"mol"`
