A plastic rod is rubbed against a wool shirt, thereby acquiring a charge of -1 µC.Thus there will transfer of electron take place.So problem is to find how  many electrons will  transfer from the wool shirt to the plastic rod?

Since we know 1C  charge acquired when `1.6xx10^19`  electrons transfered.

Since

`1 C=10^6 mu C`

Thus

`10^6 mu C `  acquired when `1.6xx10^19` electrons transfered.

`1 mu C `  accuired when `(1.6xx10^19)/10^6`  electrons transfered which equal to

=`1.6xx10^(19-6)`

`=1.6xx10^13`

Thus in acquiring `-1 mu C` charge there will `1.6xx10^13` electrons will transfer from wool shirt to plastic rod.
