Answer:
The pH would be 1.
Explanation:
The pH of an acid can be found by using the formula pH = - log [H⁺]. This was a method developed to be able to measure the pH of substances.
Since the concentration of HNO₃ is 0.1 M, then it also means that the concentration of H⁺ ions is 0.1 M.
By substituting for the formula: pH of 0.1 M HNO₃ = - log [0.1]
= 1
Answer:

Convert metres to feet:
343m*3.28f = 1,125.04ft/s
There are 3600 (60 seconds * 60 minutes) seconds in an hour. Therefore, use this number to convert to an hour.
1,125.04ft*3600s = 4,050,144 ft/h
Now, since you asked for miles, convert to miles (5280 ft in a mile):
4,050,144ft/5,280m = 767.072mph
That is your answer! Hope I helped. :)
