The mass displayed by Dina's calculator, \(1.67 \times 10^{-21}\) grams, is the mass of 1000 protons. To express this mass in scientific notation for clarity, we note that:

\[ 1.67 \times 10^{-21} \]

is already in scientific notation. If you want to express it in a more standard way, it remains the same as:

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

Therefore, the mass of 1000 protons in scientific notation is:

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