The mean absolute deviation is the average of the positive distances of each point from the mean. The larger the MAD, the greater variability there is in the data (the data is more spread out). The MAD helps determine whether the set's mean is a useful indicator of the values within the set.
95 - 98+. Although Potassium only has two stable isotopes (K-39 and K-41), the long-lived radioisotope K-40 is often also regarded as a stable isotope. Potassium Isotopes, mainly K-40 and K-41, are used to study the impact of potassium on the growth of plants and of the human cardiovascular system.
Potassium lactate is also a potassium salt, but it not commonly used as a nutritional supplement. Chemical Composition According to the United States Food and Drug Administration, potassium lactate is a white odorless solid that attracts water from the air. Its molecular formula is C3H5KO3 and its molecular weight is 128.17. It is prepared by using a chemical called potassium hydroxide to neutralize lactic acid.
