How many molecules are contained in 1.30
mol O2?
Answer in units of molec.
See you NO and NH3 problem above.
two
To find the number of molecules in a given amount of substance, you can use Avogadro's number, which is approximately 6.022 x 10^23 molecules/mol.
To calculate the number of molecules in 1.30 mol of O2, you can multiply the moles of O2 by Avogadro's number:
Number of molecules = (1.30 mol O2) * (6.022 x 10^23 molec/mol)
Calculating this gives us:
Number of molecules = 7.8266 x 10^23 molec
Therefore, there are approximately 7.8266 x 10^23 molecules in 1.30 mol of O2.
