6. The pH of a substance equals -log [H+], where [H + ] is the concentration of hydrogen ions. The concentration of hydrogen ions in pure water is 10^-7 and the concentration of hydrogen ions in
a sodium hydroxide solution is 10^-14. What is the difference of the ph levels of pure water and
sodium hydroxide solution?* LS

step-by-step explanation:

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

the answer would be the first one, the box plot will have its right tail longer than the left tail because a few exceptionally high prices make the distribution skewed to the right.
