The mass of a single atom of an element M is 3.15 xx 10^(-23) g . What is its atomic mass ? What could the element be ? |
|
Answer» Solution :Gram - atomic mass = mass of `6.022 xx 10^(-23)` atoms = mass of 1 ATOM `xx 6.022 xx 10^(-23)` `= (3.15 xx 10^(-23) G) xx 6.022 xx 10^(23) = 3.15 xx 6.022 g = 18.97 g` `therefore` atomic mass of the element = 18.97 THUS , the element is most likely to be fluorine . |
