Final answer:
To calculate the number of moles of hydrogen in 3.35 moles of C9H8O4, multiply 3.35 by the number of hydrogen atoms per mole of C9H8O4, which is 8, yielding 26.8 moles of hydrogen.
Step-by-step explanation:
The question is asking for the number of moles of hydrogen present in 3.35 moles of C9H8O4. Each molecule of C9H8O4 contains 8 moles of hydrogen atoms. Therefore, to find out how many moles of hydrogen atoms are in 3.35 moles of C9H8O4, we need to multiply the number of moles of C9H8O4 by the number of moles of hydrogen atoms per mole of C9H8O4.
This can be calculated as follows:
- Number of hydrogen atoms per mole of C9H8O4 = 8
- Number of moles of C9H8O4 = 3.35
- Total moles of hydrogen atoms = 3.35 moles of C9H8O4 × 8 moles of hydrogen/mol of C9H8O4 = 26.8 moles of hydrogen
