Question

how many molecules are there in 5000 liters of o2​

Answer 1

Answer:

At STP, every one mole of gas occupies a volume of 22.4 L or 22400 mL.

Hence 500 mL= 500/22400 moles =0.022 moles

1 mole =6.022 X 10^23 molecules

=> 0.022 moles= 6.022 X 0.022 X 10^23 molecules= 1.32 X 10^22 molecules.

pls pls pls mark me brainliest pls pls I need it pls

Answer 2

Answer:

I will tell you the process. find molar mass of 02.then multiply by 5000 and divide by Avogadro's constant(6.022)apprix
