Determine the mass of the following :
(i) `6.022 xx 10^(23)` number of `O_(2)` molecules
(ii) `6.022 xx 10^(23)` number of `O` atoms .

Text Solution

Verified by Experts

(i) The number of moles = `("number of molecular")/("Avogadro constant") = (6.022 xx 10^(23))/(6.022 xx 10^(23)) = 1`.
Now , mass = mole `xx` molecular mass = `1 xx 32 = 32` g
(ii) The number of moles `= ("number of atoms")/("Avogadro constant") = (6.022 xx 10^(23))/(6.022 xx 10^(23)) = 1` .
Now , mass = mole `xx` atomic mass = `1 xx 16 = 16` g
