Question

find the number of oxygen atoms present in 2 moles of HNO3

Answer 1

$\Longrightarrow{\boxed{\bold{Answer:3.6 \times 10^{24}\:atoms }}}$

$\textbf{\underline{Step-by-step explanation :- }}$

In $HNO_3$, there are 3 atoms of Oxygen.

Since 1 mole have = 6.022 × 10²³ atoms

2 mole will have = 6.022 × 2 × 10²³ atoms

= 12.04 × 10²³ atoms

Then 3 atoms of hydrogen will have

= 12.04 × 3 × 10²³ atoms

= 36.12 × 10²³ or approx

$\bold{\huge{= \underline{3.6 \times 10^{24}\:atoms}}}$

Answer 2

Answer:

3.6*10^23 atoms
