What is the ph of a 0.01 m solution of the strong acid hno3 in water?

Answer is: pH of a 0,01 M solution is 2.
c(HNO₃) = 0,01 M = 0,01 mol/L.
pH = -log(c(HNO₃).
pH = -log(0,01 mol/L).
pH = 2.
pH is a numeric scale used to specify the acidity or basicity of an aqueous solution. If pH is less than seven, than solution is acidic and if pH is greater seven, solution is basic, if pH is equal seven, solution is neutral.

The pH = - log (H+)
a 0.01 solution of a strong acid HNO3 in water contains 0.01 M of hydrogen ions(H+)
Therefore, pH = - log (0.01)
                       = 2
Therefore, the pH is 2

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
