Problem

The magnitude of the charge on one electron is

1.6\times10^{-19}\,\text{C}

. What is the total charge, in microcoulombs

(\mu\text{C})

, carried by

2.5\times10^{12}

electrons? Express your answer in scientific notation. a)

4.0\,\mu\text{C}

4.0\times10^{-2}\,\mu\text{C}

4.0\times10^{-1}\,\mu\text{C}

3.2\times10^{-1}\,\mu\text{C}
