Aloe vera is obtained from the aloe plant and can ease pain

Aloe vera is obtained from the aloe plant and can ease pain when applied to cuts on skin or sunburns. It has a pH of 6.10.

What is the molar concentration of [H₃O⁺] in aloe vera?

Answer      (Provide your answer with three significant figures. Answer may be in long form or scientific notation. The form of 0.123 in scientific notation is 1.23e-1, where \"e\" represents \"x10\" and the number after the \"e\" is the exponent term.)

Solution

Answer:
[H3O + ] = 10 ^-­pH   

[H3O + ] = 10 ^6.10

[H3O + ] = 7.943 x 10 ^-7

[H3O + ] = 7.943 x 10 ^-7 M
