Answer:

You know that one electron has a charge of 1.6×10−19C so we need to remove:

6.4×10−71.6×10−19=4×1012 electrons

Explanation:

You know that one electron has a charge of 1.6×10−19C so we need to remove:

6.4×10−71.6×10−19=4×1012 electrons

Since one electron has a charge of 1.6⋅10−19C we can simply take the overall charge of the sphere and divide it by the charge of a single electron to see how many electrons account for the overall charge. It would look like

6.4⋅10−4C1.6⋅10−19C

Which would give us 4⋅1012electrons
