What is the difference expressed in kilograms between the mass of proton and the mass of electon?

The difference in mass between a proton and electron is 1.672*10⁻²⁷ kg

Explanation:

Mass of a proton =

Mass of an electron =

The difference in mass between a proton and electron is:

Convert g to kg

10³ g = 1 kg

The difference in mass in units of kg would be:

screening

explanation:

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
