To express a number in scientific notation, we need to move the decimal point so that there is only one non-zero digit to the left of the decimal point.
In this case, we can move the decimal point two places to the right to get 1.67.
So, the mass of 1,000 protons in scientific notation is 1.67 × 10^-21 grams.
