= 0.88 g / cm³
Since the density of water is greater than the density of the boat ( 1 > 0.88) then that means, the boat will NOT sink.

Answer:
2.15
Explanation:
For this question, we have to remember the <u>pH formula</u>:
By definition, the pH value is calculated when we do the -Log of the concentration of the <u>hydronium ions</u> (). So, the next step is the calculation of the <u>concentration</u> of the hydronium ions. For this, we have to use the <u>molarity formula</u>:
We already know the number of moles (0.0231 moles) and the volume (3.33 L). So, we can plug the values into the molarity formula:
With this value, now we can calculate the pH value:
<u>The pH would be 2.15</u>
