To break down the formula for citric acid (CH₂COOH):

  • C (carbon) appears 3 times.
  • H (hydrogen) appears 6 times.
  • O (oxygen) appears 4 times.

Let’s put this in a table format as you described:

| Element | Number of Atoms | |-----------|------------------| | Carbon | 3 | | Hydrogen | 6 | | Oxygen | 4 |

Here’s how the elements and their quantities relate to the options provided:

  • Carbon: 3
  • Hydrogen: 6 (You provided 2, but it's 6 total)
  • Oxygen: 4 (You provided 3, but it's 4 total)

Since the numbers you provided as options (1, 2, 3, 7) do not correctly match the elemental counts in the molecule, here is the correct breakdown according to the chemical formula.

Note that in terms of identifying how many of each element there are based on atomic symbols, it is important to analyze each part of the molecular formula accurately. Would you like help with anything else related to this?
