There are #7.377xx"10"^23"# carbon atoms in #"1.225# moles of carbon.

Explanation:

One mole of anything has #6.022xx10^23# anythings, including atoms. You may recognize this as Avogadro's number. To determine the number of atoms in #"1.225 moles carbon"#, multiply the moles by #6.022xx10^23"atoms/mol"#.

#1.225color(red)cancel(color(black)("mol C"))xx(6.022xx10^23"atoms C")/(1color(red)cancel(color(black)("mol C")))=7.377xx"10"^23" atoms C"#

Well, how many particles in ONE MOLE?

Explanation:

#"1 mole"# specifies #6.022xx10^23*"individual particles"#..

And so .............

#"number of carbon atoms"-=1.225*molxx6.022xx10^23*mol^-1=7.38xx10^23*"carbon atoms"#
