Answer:
![[H^+]=1*10^(-3)M](https://img.qammunity.org/2023/formulas/chemistry/college/pia38gehcbh0an870zmhsexj5532vp9u8x.png)
Explanations:
The formula for calculating the pH of the drink is expressed as:
![pH=-log[H^+]](https://img.qammunity.org/2023/formulas/chemistry/college/awlfu4vc4iesv0xee9hm70iq5p6gwfz7kw.png)
where:
[H+] is the hydrogen ion concentration
Given the following parameters
pH of the drink = 3.0
Substitute into the formula
![\begin{gathered} 3.0=-log[H^+] \\ -3.0=log[H^+] \\ [H^+]=10^(-3) \\ [H^+]=1*10^(-3)M \end{gathered}](https://img.qammunity.org/2023/formulas/chemistry/college/k47y1pc2b6qp7bxantmchr22zx9vhc5mzn.png)
Hence the hydrogen ion concentration of the drink is 1 * 10^-3M
