Final answer:

There are 3.174 × 10²² hydrogen atoms in 5.29 × 10²¹ molecules of ethanol (CH₃CH₂OH).

Step-by-step explanation:

To find the number of hydrogen atoms in 5.29 × 10²¹ molecules of ethanol (CH₃CH₂OH), we need to determine the number of hydrogen atoms in one molecule of ethanol and then multiply it by the total number of molecules.

The molecular formula of ethanol (CH₃CH₂OH) consists of 6 hydrogen atoms. Therefore, in one molecule of ethanol, there are 6 hydrogen atoms.

To calculate the total number of hydrogen atoms in 5.29 × 10²¹ molecules of ethanol, we multiply the number of hydrogen atoms in one molecule (6) by the total number of molecules (5.29 × 10²¹). This gives us (6) × (5.29 × 10²¹) = 3.174 × 10²² hydrogen atoms.
