Final answer:
To find the moles of hydrogen in the sample, we multiply the moles of carbon (6.2) by 8 (the hydrogen to carbon ratio in the molecule) to get 49.6 moles of hydrogen.
Step-by-step explanation:
The molecular formula for the compound CH3OC(CH3)3 indicates that for each carbon (C) atom, there are 8 hydrogen (H) atoms in the molecule. Since there are 6.2 moles of carbon in the sample, we can calculate the moles of hydrogen by multiplying the moles of carbon by 8 (the ratio of H to C atoms in the molecule).
Moles of hydrogen = 6.2 moles of C × 8 = 49.6 moles of H.
Therefore, the sample contains 49.6 moles of hydrogen.
