How to Express the Mass of a Proton in Scientific Notation

What is the mass of a proton?

The mass of a proton is 0.000 000 000 000 000 000 000 000 000 001675 kg. How can we express this mass in scientific notation?

Answer:

The mass of a proton is 1.675 x 10^-27 kg when expressed in scientific notation.

To express the mass of a proton in scientific notation, we need to identify the number of places the decimal point has to be moved until we get a number between 1 and 10. From the given mass of a proton, 0.000 000 000 000 000 000 000 000 000 001675 kg, we need to move the decimal point 27 places to the right to get the number 1.675. Therefore, the mass of the proton in scientific notation is 1.675 x 10^-27 kg.

Scientific notation is a way of expressing numbers as a coefficient multiplied by 10 raised to a power. It is commonly used to represent very large or very small numbers in a more manageable format.
