What is the volume occupied by 4 grams of oxygen at room temperature

volume of O2 = 3000cm³

Explanation:

no. of moles= mass of oxygen (g)/molar mass of oxygen(g/mol)

                    = 4/32

                    =0.125

volume of oxygen= no. of moles × 24000 cm³ (or 24dm³)

                             = 0.125 × 24000 cm³  

                             =3000cm³  (or 3dm³)

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
