8 g O_(2) has the same number of molecules as

Answer»

7 g CO
`14gN_(2)`
`11gCO_(2)`
`16gSO_(2)`

SOLUTION :`8gO_(2)=(8)/(32)mol=0.25mol.`
`7gCO=(7)/(28)=0.25mol,`
`14gN_(2)=(14)/(28)=0.5mol.`
`11gCO_(2)=(11)/(44)=0.25mol.`
`16gSO_(2)=(16)/(64)=0.25mol.`
Equal moles contain equal number of MOLECULES.
