Chemistry mole question

Question

freon-12 (cf2cl2) is commonly used as the refrigerant in central home air conditioners. Calculate, at STP, the volume of freon-12 of a sample containing 5.82 x 10^13 atoms

Answer 1

Hello, Yoon,

5.82 x 10^13 atoms can be converted into moles by Avogadro's number of 6.022x10²³ atoms/mole. I get a really low number of moles: 9.66x10^-11 , so check my calculation. At STP. a mole of any gas occupies 22.4 liters/mole. So multiply the number of moles by 22.4 to yield liters. (2.16x10^-9 liters)!
