Question 1126577: (1 point) The pH of lemon juice is about 2.7.
(a) What is the concentration of hydrogen ions in lemon juice?
The concentration is _______moles per liter. [Hint: pH = −log[H+] ]
(b) A person squeezes 3 oz of lemon juice into a cup. Based on your answer to part (a), how many hydrogen ions does this juice contain? Your answer should be a very large number, so in order to fit your answer in the box, you should use scientific notation. For example you could enter 2.45×1018 by entering 2.45 * 10^(18) instead of 2,450,000,000,000,000,000.
Number of ions: ____ ions. [Hint: 1 liter = 30.3 ounces, and one mole of Hydrogen ions is 6.02×1023 Hydrogen ions. Note that the concentration you found in (a) is given in moles per liter.]
