In Exercises 53–56, use the acidity model

\(\mathbf{p H}=-\log \left[\mathbf{H}^{+}\right]\)

where acidity (pH) is a measure of the hydrogen ion concentration \(\left[\mathbf{H}^{+}\right]\) (in moles of hydrogen per liter) of a solution.

A grape has a pH of 3.5, and baking soda has a pH of 8.0. The hydrogen ion concentration of the grape is how many times that of the baking soda?
