Dina computed the mass of 1,000 proton grams. The calculator displayed the number 1.67E-21. What is the mass of 1,000 protons in scientific notation?
The mass of 1 proton is approximately 1.67 x 10^-24 grams.
Therefore, the mass of 1,000 protons would be:
1.67 x 10^-24 grams/proton * 1,000 protons = 1.67 x 10^-24 * 1,000 = 1.67 x 10^-21 grams
So, the mass of 1,000 protons in scientific notation is 1.67E-21 grams.
