1.83 x 10$^{3}$ electrons

Work Step by Step

A proton has a mass of 1.67 x 10$^{-21}$ kg and an electron has a mass of 9.11 x 10$^{-31}$ kg. Use these as conversion factors in order to determine the number of electrons required. = $1 proton \times \frac{1.67 \times 10^{-21} kg}{1 proton} \times \frac{1 electron}{9.11 \times 10^{-31} kg} $ = 1.83 x 10$^{3}$ electrons
