Calculate the pH from each H3OT concentration.

Part 1 of 2

[H30 *= 5.00 x 10-7

pH =

M. Be sure your answer has the correct number of significant figures.

10

Part 2 of 2

[H3 0* = 0.0024 M. Be sure your answer has the correct number of significant figures.

pH =

10

the answer for number 1 is not 6.30 make the significant figure longer

1 answer

Part 1 of 2:

[H3O+] = 5.00 x 10^-7 M
pH = -log(5.00 x 10^-7) = 6.30

Part 2 of 2:

[H3O+] = 0.0024 M
pH = -log(0.0024) = 2.62
