Question

Calculate the number of atoms in 11.2 litre of So2 gas at STP

Answer 1

hey there

at STP
No. of moles = given vol.(litres) / 22.4

so here no. of moles of SO2 gas = 11.2/22.4
= 0.5 moles
and 1 mole has 6.022 ×10^23 atoms
so number of atoms in 11.2 litre of So2 gas at STP = 0.5 × 6.022× 10^23 atoms
= 3.011 × 10^23 atoms


hope it will help you
