हिन्दीWhat is the mass of one carbon-12 atom in grams as determined by mass spectrometry?
Correct answer · Option 2
\( 1.992648 \times 10^{-23} \text{ g} \)
Explanation
Mass of one \( ^{12}\text{C} \) atom = \( \frac{12 \text{ g/mol}}{6.0221367 \times 10^{23} \text{ atoms/mol}} = 1.992648 \times 10^{-23} \text{ g} \).
