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 point)

Question

1.67 x grams

Answer 1

To express the mass of 1,000 protons in scientific notation, we notice that the calculator displayed \( 1.67E-21 \), which means \( 1.67 \times 10^{-21} \) grams.

Thus, the mass of 1,000 protons in scientific notation is:

\[ 1.67 \times 10^{-21} , \text{grams} \]

So, in your question, you would fill in the answer as:

1.67 x \( 10^{-21} \) grams.
