How many times higher is the concentration of H+ in the Hubbard Brook sample than in unpolluted rainwater?

1. 7 (a neutral solution)

10-7= 0.0000001 moles per liter

2. 5.6 (unpolluted rainwater)

10-5.6 = 0.0000025 moles per liter

3. 3.7 (first acid rain sample in North America)

10-3.7 = 0.00020 moles per liter

The concentration of H+ in the Hubbard Brook sample is 0.00020/0.0000025, which is 80 times higher than the H+ concentration in unpolluted rainwater.

Explanation:

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
