we know ,
charge of 1 electron = 1.6 × 10^-19 C
so, charge of 5 × 10¹³ electrons = 1.6 × 5 × 10^13 × 10^-19 = 8 × 10^-6 C =8 uC
so , 8 uC charge transfered from sphere . so,
net charge = -6.5 + 8 = 1.5 uC
charge of 1 electron = 1.6 × 10^-19 C
so, charge of 5 × 10¹³ electrons = 1.6 × 5 × 10^13 × 10^-19 = 8 × 10^-6 C =8 uC
so , 8 uC charge transfered from sphere . so,
net charge = -6.5 + 8 = 1.5 uC
