Final answer:
The mass of 1,000 protons, by multiplying the mass of a single proton (1.67 × 10^-27 kg) by 1,000, is 1.67 × 10^-24 kg. The multiple-choice options provided do not match this calculation, indicating a possible error in the options given.
Step-by-step explanation:
The question asks for the mass of 1,000 protons. We know that the mass of a single proton is 1.67 × 10-27 kg. To find the mass of 1,000 protons, we multiply the mass of one proton by 1,000.
1.67 × 10-27 kg/proton × 1,000 protons = 1.67 × 10-24 kg
The result is not listed among the options provided in the question, but the method of calculation is correct and is an important example of using scientific notation to express numbers. However, based on the options given, we might infer that a typo occurred in the question, and the correct option that approximates the calculated mass of 1,000 protons is 1.67 × 10-24 kg, which is not listed.
