During a certain time period, 4.0 million tons of SO 2 was released into the atmosphere and was subsequently oxidized to SO 3 . As explained in the FYI , the acid rain produced when the SO 3 dissolves in water can damage marble statues: CaCO 3 ( s ) + H 2 SO 4 ( a q ) → CaSO 4 ( a q ) + CO 2 ( g ) + H 2 O ( l ) (a) How many 500 pound marble statues could be damaged by the acid rain?

Solution Summary: The author explains how the number of marble statues damaged by the acid rain should be calculated under the condition that the statue is considered as damage.
During a certain time period, 4.0 million tons of SO2 was released into the atmosphere and was subsequently oxidized to SO3. As explained in the FYI, the acid rain produced when the SO3 dissolves in water can damage marble statues:

The acidity of a solution is measured by its pH.
If HT| represents the concentration of hydrogen ions (in moles/liter) in the solution,
the pH is defined by pH = – log H+
Based on careful measurements and calculations, a chemist examines two solutions and asserts:
"The hydrogen ion concentration of Solution A
is 37.93% greater than the hydrogen ion concentration of Solution B."
If the pH of solution B is 4.36, determine the pH of Solution A.
Report your answer to two decimal places.
Solution A has pH equal to
