  • Calculate the number of molecules of carbon dioxide present in 4.4g of carbondioxide.

Calculate the number of molecules of carbon dioxide present in 4.4g of carbondioxide.

Answers (1)

Weight of CO2 in gram per moles =(12) + (16*2) = 12+32 = 44 g/moles.
Now, for 4.4 grams of CO2, we get:
4.4/44 = 0.1 moles
Now, number of molecules:-
0.1 x 6.022 x 1023 = 0.6022 x 1023 = 6.022 x 1022 molecules.
