Answer to Question #70655 in General Chemistry for amber

Question

Calculate the number of CO2 molecules in 2.44×10−2 mole of CO2.

Answer 1

N = n*Na Avogadro constant (Na) - is the number of particles, usually atoms or molecules, that are contained in the amount of substance given by one mole
Na = 6,02*10^23 mole^-1

N= 2.44*10^-2*(6.02*10^23) = 1.47*10^22 molecules
