This problem is providing us with the mass of hydrochloric acid and the volume of solution and asks for the pH of the resulting solution, which turns out to be 1.477.
<h3>pH calculations</h3>
In chemistry, one can calculate the pH of a solution by firstly obtaining its molarity as the division of the moles of solute by the liters of solution, so in this case for HCl we have:

Next, due to the fact that hydrochloric acid is a strong acid, we realize its concentration is nearly the same to the released hydrogen ions to the solution upon ionization. Thereby, the resulting pH is:

Which conserves as much decimals as significant figures in the molarity.

Social interactions help lower the risk of Alzheimer diseases by stimulating the brain. Many studies show that if you use your brain more you have a lower chance of getting Alzheimer's.
The answer to this question is (13811384) Joules.
Hi. 2fouls! :)
First convert the number from kilometer to miles:


Now to find the miles per minutes,divide the miles per hours by 60 (the amount of minutes in an hour.)


The car is travelling at a speed of 0.860766667 miles/minute.
Hope this helps.
