Answer:
1370moles
Explanation:
Given parameters:
Number of molecules in methane = 8.25 x 10²⁶molecules
Unknown:
Number of moles of methane = ?
Solution:
A mole of any substance contains the Avogadro's number of particles which is 6.02 x 10²³molecules;
6.02 x 10²³ molecules is contained in 1 mole of a substance
8.25 x 10²⁶molecules of methane will contain = 1370moles
The answer is A. The pH decreases
