If `16 g` of oxygen contains 1 mole of oxygen atoms, calculate the mass of one atom of oxygen.

Text Solution

Verified by Experts

One mole of oxygen contain atoms =`N_(A)=6.022xx10^(23)`
`6.022xx10^(23)` atoms of oxygen have mass=16g
1 atom of oxygen has mass=`=((16g))/(6.022xx10^(23))=2.657xx10^(-23)g`
