Consider the following graph of % abundance as mass of lead

The relative atomic mass of lead is

A

208

B

`207.567`

C

`207.302`

D

`209`

Text Solution

Verified by Experts

The correct Answer is:
C
The relative atomic mass of lead
` = ( 206 xx (23.6 )/(100) + 207 xx ( 22.6 )/(100) + 208 xx (53.8)/(100) )`
`=(48.616 + 46.782 + 111.904 )`
` = 207.302 u`
