Calculating charge on a body with excess of electrons

How would I calculate the charge on a small sphere with an excess of 5.0 x 10 ¹⁴ electrons?

Answer:

We know that charge on an electron is (-) 1.6 x 10^-19 C

If the sphere has 5.0 x 10 ¹⁴ electrons in excess then the body has a net negative charge and is given by q = ne

Charge on the sphere = 5.0 x 10 ¹⁴ x (-) 1.6 x 10 ^-19 = 8 x 10 ^-5 C
