Question

calculate the mass of N2 which contains same number of molecules as a present in 4.4 grams of carbon dioxide​

Answer 1

Explanation:

n2 mass=14gm/mole

same number of co2 molecule as a present in 4.4gm

co2 mass=44gm/mole

therefore 4.4/44=0.1mole

1mole molecule present in co2=6.022*10^23

therefore, 6.022*10^23*0.1

=6.022*10^23 molecule present in co2

plz mark the brilliant answer

Answer 2

N2 mass =14gm/mole

same number of co2 molecule as a present in 4.4gm

co2 mass=44gm/mole

therefore 4.4/44=0.1mole

1mole molecule present in co2=6.022*10^23

therefore, 6.022*10^23*0.1

=6.022*10^23 molecule present in CO2
