A balloon contains 0.15 moles of co2 gas. how many molecules of co2 are in the balloon?
2 answers:
The number of atoms or molecules in one mole of a substance is defined as Avagadro's number
The Avagadro's number is 6.023 X 10^23 atoms / molecules
Given:
The moles of carbon dioxide = 0.15 moles
In order to calculate the number of molecules in given moles of carbon dioxide we will multiply the given moles with Avagadro's number as
Number of molecules = 0.15 X 6.023 X 10^23
Number of molecules = 9.035 X 10^22 molecules of carbon dioxide
1- One mole is = 6.02 x 10^23 of anything, So one mole of atoms is 6.02x10^23.
2- when the balloon contains 0.15 moles of Co2 gas so:
the no.of molecules of Co2 = 0.15 x 6.02x 10^23
= 9.0 x 10^22
