Question

5.6 litre of co2 at stp contains how many atoms

Answer 1

Answer:

Hello mate

According to avogadro's law 22.4l at STP of any element or compound contain 6.023×10²³particles(avogadro's constant)

⇒22.4l of CO2=6.023×10²³molecules

⇒5.6l of CO2=6.023×10²³/4molecules

≈1.5×10²³molecules

each molecule of CO2 has 3 atoms , total number of atoms is

1.5×10²³×3=4.5×10²³atoms

Hope the qn is answered
