-log(1.0 X 10^-4 M KOH)
= 4
14 - 4
= 10 pH KOH
----------------
No it is ten to the negative fourth power. If the number is greater than 1 it is to a positive power, if the number is smaller thann 1 it is to a negative power.
From the abbreviation of "power of Hydrogen" pH is the negative, base ten logarithm of the hydronium ion (H3O+) concentration in a solution. The concentration of the hydronium ion in a solution that has a pH of 7.5 is 1 x 10-7.5 Molar (moles per liter).
No
The "p" represents the "Negative Logarithm", and the "H" stands for the molar concentration of dissolved hydrogen ions. It is unknown what the "p" actually stands for, but some suggest "Power of Hydrogen" ("potenz" means power in German), other suggest it stands for "potential".
By the definition of molarity, a 2.0 molar solution contains twice Avodagro's Number of molecules per liter. Therefore, the stated solution contains 0.300X2X6.022Xten to the 23rd power = 3.6X ten to the twenty-third power sugar molecules. (Only two significant digits are justified, because the molarity is specified with only two significant digits.)
Negative one half to the fourth power equals 0.0625
i think it is either 10-9 or 10x10-9 (standard form)
0.0001
2-4 = 16
Five to the negative 4th power = 5-4 = 625
No it is ten to the negative fourth power. If the number is greater than 1 it is to a positive power, if the number is smaller thann 1 it is to a negative power.
+1/81
1/8
It doesn't. Negative one to an even power equals positive one. Negative one to an odd power equals negative one.
the answer would be .000X because if the power is negative than the answer will be a decimal.
0.25^-1 = 4
one over six to the fourth
