Answer:

Step-by-step explanation: To calculate the pH of a solution, use the equation

p

H

=

−

log

[

H

3

O

+

]

Since we are given the hydronium ion (

H

3

O

+

) concentration of the solution, we can plug this value into the formula.

p

H

=

−

log

[

1.00

×

10

−

4

M

]

p

H

=

4

The pH of this solution is 4.

Added notes:

p

H

=

p

H

3

O

+

because hydrogen ions attach to water molecules for form hydronium ions.

Some other key things to remember for pH calculations include:

pH + pOH = 14

pH = -log[

H

+

]

pOH = -log[

O

H

−

At Adam's Hats, there are 52 baseball caps and 13 other hats. What percentage of the hats are baseball caps?
Solnce55 [7]

Total hats = 52 + 13 = 65

Percentage that are baseball = number of baseball/ total hats x 100.

52/65 = 0.8 x 100 = 80%

80% are baseball hats
