Question

what will be the answer​

Answer 1

(a) no. of moles in 6.023 * 10²³ particles= 1

no. of moles in 24.088 * 10²³ (6.023*10²³ * 4) particles =  4

(b) molar mass of CO₂ = 12+32= 44

moles in 22g = 22/44 =0.5

Answer 2

In 1 mole of CO2, 6.023*10^23 particles are present.

Here 24.088*10^23 particles is given,so 24.088*10^23÷6.023*10^23= 4 moles
