The mass of an electron is 9 x 10-28 grams. A proton weighs 1,836 times as much as an electron. Express the weight, in grams, of a proton in scientific notation.

Answer 1

Actually, you are asking for the MASS of the proton, not its weight.

m = 1836(9 x 10^-28) g = 1.6524 x 10^-24 g

You may want to round off.
