Dina computed the mass of 1,000 protons in grams. The calculator displayed the number 1.67E−21. What is the mass of 1,000 protons in scientific notation?
1.67 × grams
In scientific notation, the number 1.67E−21 is written as 1.67 × 10^(-21).
Therefore, the mass of 1,000 protons in scientific notation is 1.67 × 10^(-21) grams.
To convert the number to scientific notation, we need to move the decimal point to the right until we have a number between 1 and 10.
In this case, we need to move the decimal point 21 places to the right.
Thus, the mass of 1,000 protons in scientific notation is 1.67 × 10^(-21) grams.
