The mass of an electron is approximately 9.1 x 10 to the negative 31 power. The mass of a proton is approximately 1.7 x 10 to the negative 27th power. Approximately how many times greater is the mass of a proton than the mass of an electron?

a) 5.35 x 10^57 times greater
b) 9.1 x 10^-31 times greater
c) 5.35 times greater
d) 1.7 x 10^-27 times greater

Final answer:

The mass of a proton is approximately 1.87 x 10³ times greater than the mass of an electron.

Step-by-step explanation:

The mass of a proton is approximately 1.7 x 10-27 kg, while the mass of an electron is approximately 9.1 x 10-31 kg. To find how many times greater the mass of a proton is than the mass of an electron, we can divide the mass of the proton by the mass of the electron.

1.7 x 10-27 kg / 9.1 x 10-31 kg = 1.87 x 103

Therefore, the mass of a proton is approximately 1.87 x 103 times greater than the mass of an electron.
