<u>Answer:</u>
concentration of H ions = 0.0001 M
<u>Explanation:</u>
Base 10 logarithm of the H+ concentration when multiplied by -1 is equal to the pH value of a solution. By reversing this formula, we can find the concentration of the H+ in the solution:
pH = ㏒
or = concentration of H+
We know that, pH of the solution is 4.0,
so =
Therefore, the concentration of Hydrogen ions in a solution of pH = 4 is 0.0001 M.
I think it's <em>80 . 12</em>
pls tell me if correct
Answer:
The boiling point of a liquid is the temperature at which its vapor pressure is equal to the pressure of the gas above it.The normal boiling point of a liquid is the temperature at which its vapor pressure is equal to one atmosphere (760 torr). Microscopic view inside a bubble in boiling water.

Explanation:
According to Avagadros law 1 mole of a substance contains 6.02 × 10^23 particles.
Thus, 1 mole of C6H14 contains 6.02 × 10^ 23 molecules,
Therefore, 9.25 × 10^24 molecules will have;
(9.25 × 10^24)/ (6.02 ×10^23)
= 15.365 moles.
