How many atoms of oxygen are there in lemon juice?

Lemon juice primarily consists of water, citric acid, and various other compounds. The main component, citric acid (C6H8O7), contains seven oxygen atoms per molecule. Given that lemon juice is mostly water (H2O), each molecule of water has one oxygen atom. Therefore, the total number of oxygen atoms in lemon juice depends on the concentration of citric acid and water, but it typically contains a significant number of oxygen atoms due to these compounds.
