The mass of a proton is approximately \( 1.67 \times 10^{-27} \) kg, while the mass of an electron is about \( 9.11 \times 10^{-31} \) kg. To find out how many times greater the mass of a proton is than the mass of an electron, you can divide the mass of the proton by the mass of the electron:
\[
\frac{1.67 \times 10^{-27} \text{ kg}}{9.11 \times 10^{-31} \text{ kg}} \approx 1836
\]
So, the mass of a proton is about 1,836 times greater than the mass of an electron. Among the options given, the closest answer is **1,800 times**.
\[
