Final answer:
The pH of a solution with a hydrogen ion concentration of (4.7 * 10⁻²) moles per liter is 1.33.
Step-by-step explanation:
The pH of a solution with a hydrogen ion concentration of (4.7 * 10⁻²) moles per liter can be calculated using the formula pH = -log[H+]. In this case, the hydrogen ion concentration is 4.7 * 10⁻² M. Taking the negative logarithm of this concentration gives a pH of 1.33.
