Question

what are the avagadro's number of particles in 0.25 moles of co2 ?​

Answer 1

Answer:

One-quarter (0.25) molecule cannot exist, but one molecule CO2 is 44 amu [12 +2(16)].

One mole of CO2 (Avogadro’s Number or 6.02 x 10e23 molecules) is 44 g and thus 0.25 mole = 11 g for 1.5 x 10e23 molecules of CO2
