Question

Calculate the no. Of total atoms of nitrogen gas if it occupies 224 ml

Answer 1

if it occupies 224 ml

then

no. of moles =

$\frac{given \: volume}{22.4}$

so. no. of moles of nitrogen gas is 10 moles

now, no. of nitrogen molecules = 10 × 6.022 ×10²³

and 1 molecule of nitrogen contain 2 atoms hence, 6.022× 10²⁴ molecules will contain = 2 × 6.022 ×10²⁴

it answer is 12.044 ×10²⁴
