Question

At one time, there was a atomic mass scale on the assignment of the value 16.0000 to naturally occuring oxygen. The atomic mass of silver on this scale will be (atomic masses of silver and oxygen on the present scale are 107.868 and 15.9994 respectively).
A. `108.000`
B. `107.872`
C. `108.012`
D. `107.909`

Answer 1

Correct Answer - B
`("At. Mass of silver on old scale")/("At. mass of" .^(16)O "on old scale")`
`=("At. Mass of silver on new scale")/("At. Mass of" .^(16)O "on new scale")`
`("At. Mass of silver on old scale")/(16.000)=(107.868)/(15.994)`
At. Mass of silver on old scale
`=(107.868xx16.000)/(15.9994)=107.872`
