This is the chemical formula for acetic acid (the chemical that gives the sharp taste to vinegar):
\[
\mathrm{CH}_{3} \mathrm{CO}_{2} \mathrm{H}
\]
An analytical chemist has determined by measurements that there are 35 . moles of carbon in a sample of acetic acid. How many moles of hydrogen are in the sample?
Be sure your answer has the correct number of significant digits.
mol \( \square \)
\( \times 10 \)
