Question

one gram atom of an element contains 6.023×10²³ atom a) find the number of atoms in 8g oxygen​

Answer 1

Explanation:

$\frac{mass}{molar \: mass} = \frac{no. \: of \: atoms}{avogadro \: constant}$

$\frac{8}{16} = \frac{no. \: of \: atoms}{6.022 \times {10}^{23} }$

$no. \: of \: atoms = \frac{6.022 \times {10}^{23} }{2}$

$no. \: of \: atoms = 3.011 \times {10}^{23}$

Therefore it is your answer.

I hope it helps you. If you have any doubts, then don't hesitate to ask.
