A) \[16.2\]
B) \[17.4\]
C) \[17\]
D) \[16.5\]
Correct Answer: A
Solution :
Oxygen have \[90%\,\,{{O}^{16}}\] and\[10%\,\,{{O}^{18}}\] \[\therefore \]Atomic mass \[=\left[ \frac{90}{100}\times 16+\frac{10}{100}\times 16 \right]\] \[=\frac{1440+180}{100}=\frac{1620}{100}=16.2\]You need to login to perform this action.
