Two bubles B_(1) and B_(2) of equal capacity contain 10 g oxgyen (O_(2)) and ozone (O_(3)) respectively. Which bulb will have greater number of O-atoms and which will have greater number of molecules?

Answer»

Solution :`"10 G O"_(2)=(10)/(32)"MOLE"=(10)/(32)xx6.02xx10^(23)" molecules"=1.88xx10^(23)" molecules"`
` = 2xx1.88xx10^(23)" atoms"=3.76xx10^(23)" atoms"`
`"10 g O"_(3)=(10)/(48)" mole"=(10)/(48)xx6.02xx10^(23)" molecules"=1.254xx10^(23)" molecules"`
`=3xx1.254xx10^(23)" atoms"=3.76xx10^(23)" atoms"` ltBrgt Thus, both contain the same bumber of atoms but bulb `B_(1)` contains more NUMBER of molecules.
