molar mass of gas at STP = 22.4 litres
1 litre = 1000 ml
22.4 litre = 22.4 × 1000 = 22400 ml
molar mass of co2 at STP = 44×22400 gm
no. of moles = 56÷ 44 × 22400
= 0.11 moles
no. of molecules = moles × avogadro no.
= 0.11 × 6.022 × 10 raised to the power 23
= 66.242 × 10 raised to the power 21 molecules
hopefully it is the answer

Answer: molecules of
Explanation:
According to Avogadro's law, 1 mole of every substance occupy 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
Putting values in above equation, we get:
Thus of will contain= molecules of
