If `36.4xx10^(-15)g` of mass is transferred when fur is rubbed with silk, find the number of electrons lost by fur? (mass of electron `= 9.1xx10^(-31) ` kg ).

Explanation

`m = 36.4 xx 10^(-15) g = 36.4 xx 10^(-18) kg `
`M_(e) = 9.1 xx 10^(-31) kg `
` m = n xx m_(e)`
`n=(m)/(m_(e))=(36.4 xx 10^(-18))/(9.1 xx 10^(-31))`
`n =4 xx 10^(13)`
