One million of silver atoms weigh `1.79 xx 10^(-16)g`. Calculate the atomic mass of silver.

Answer

107.8 u

Explanation

`10^(6)` atoms of silver occupy mass `= 1.79 xx 10^(-16)g`
`6.022 xx 10^(23)` atoms of silver occupy mass `= (1.79xx10^(-16)g)/(10^(6))xx6.02xx10^(23)=107.8g`
Atomic mass of silver `= 107.8 g = 107.8 u`.
