Acidity is measured on the ph scale. the acidity of a substance is given by ph=−logh, where h is the concentration of hydrogen ions. if a substance has a ph of 6, which equation could be used to find its h value?

Step-by-step explanation:

To solve this question it is important to remember logarithm rules. That is:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

i belive those are the ones that are under 90 degreese.
