3: The negative of the logarithm (base 10) of the concentration. The logarithm of 1 is 0 and the logarithm of 10-3 is -3; the logarithm of their product is the sum of their individual logarithms, -3 in this instance, and the negative of -3 is +3.
103
103 + 500 = 603
103 + 300 = 403
158 + 103 = 261
There is no solution because there is nothing to solve.
* MT 103 plus is a subset of MT 103 * Used for STP * Only the option A is used with certain fields
79 + 103 = 182
103 + 2 = 105
78 + 25 = 103
810 + 103 = 913
1/103 = 0.001 M ========( pH 3 ) 1/105 = 0.00001 M ============( pH 5 ) As you see, a pH of 3 has a 100 times concentration of 5 pH ( 10 * 10 devalued ) This is the scale; logarithmic.
Definitely. 103 is the solution to an infinite number of different arithmetic exercises. But the only single number that's equal to 103 is . . . . . . . wait for it . . . . . . . 103.
