39.0983
How are the elements arranged by atomic mass?
They are NOT normally arranged by atomic mass; instead they are arranged in the periodic table by their atomic number. The latter is the number of protons (or electrons) in a single atom of the element and it is a constant for the element. The atomic mass is an average of the isotopes of the element (in proportion to their abundance).While the atomic number is always an integer, increases in steps of 1 and elements that are a specific "distances" apart share similar chemical characteristic. On the other hand the atomic mass is rarely an integer, and occasionally it reverses the order laid out be the periodic table: for example, element 18, argon has an atomic mass of 39.948 which is greater than that of element 19, potassium with a mass of 39.098: this is because the predominant isotope of argon has 22 neutrons while that for potassium has 20 neutrons.
20 meq is equal to how many mg of potassium?
Potassium has a gram atomic mass of 39.1, to three significant digits (one more significant digit than "20 meq" has). Therefore, one meq = 39.1 mg, and 20 meq = 20(39.1) = 7.8 X 102 mg, to the justified number of significant digits.
What is the mass of 0.41 mol of the element potassium?
The gram-atomic mass of potassium is 39.098. This number multiplied by 0.41 = 16 grams.
What is the atomic mass of potassium?
The atomic mass of potassium is 39.0893
What is the mass of 2.47 moles ofKMnO4?
The formula shows that each mole or formula unit contains one gram atomic mass of each of potassium and manganese and four gram atomic masses of oxygen. the gram atomic mass of potassium is 39.0983, that of manganese is 54.9380, and that of oxygen is 15.9994. Therefore, the required answer is: 2.47[39.0983 + 54.9380 + 4(15.9994)] or about 390 grams, to the justified number of significant digits.
