Question

On a proton is 1.6×10`¹⁹. how many protons are in one coulomb of charge​

Answer 1

Answer: There are
`6.25 * 10^(18)` protons present in one coulomb of charge​.

Step-by-step explanation:

Given: Charge on proton =
`1.6 * 10^(-19) C`

It is known that the charge on a proton is equal to the charge present on an electron.

Formula used to calculate number of protons is as follows.

Q = ne

where,

Q = charge considered

n = number of protons

e = charge on electron or proton

Substitute the values into above formula as follows.

`Q = ne\\1 C = n * 1.6 * 10^(-19) C\\n = 0.625 * 10^(19)\\= 6.25 * 10^(18)`

Thus, we can conclude that there are
`6.25 * 10^(18)` protons present in one coulomb of charge​.
