CALCULATE THE MASS OF NITROGEN WHICH CONTAINS SAME NUMBER OF
MOLECULES AS ARE PRESENT IN 4 4GM OF CO2?

Kirti Gogia · Accepted Answer

The molar mass of carbon dioxide is 44g Thus, there are 6 022 X
1023 molecules of CO2 in 44g if
CO2
So
44g of CO2 = 6 022 X 1023 molecules of
CO2
1g of CO2 = (6 022 X 1023 / 44) molecules
of CO2
4 4g of CO2 = (6 022 X 1023 X 4 4) / 44
molecules of CO2
= 6 022 X 1022 molecules of CO2
Thus, there are 6 022 X 1022 molecules of
CO2 in 4 4g of CO2 Now, the molar mass of
nitrogen gas (N2) is 28g Thus, there are 6 022 X
1023 molecules of N2 in 28g if N2
So
6 022 X 1023 molecules of N2 = 28g of
N2
1 molecule of N2 = 28 / (6 023 X 1023) g
of N2
So, 6 022 X 1022 molecules of N2 = (28 X 6
022 X 1022) / (6 022 X 1023) g of
N2
= 2 8g of N2
