Since potassium chloride has the formula KCl and the mass of the lost electron from neutral potassium is negligible compared with the mass of the protons and neutrons in the potassium atom nucleus, the molecular mass of potassium in this compound is the same as the atomic mass of potassium, 39.098.
The separate components of this compound, potassium hydrogen phthalate are one potassium, five hydrogen, eight carbon and four oxygen atoms. The total molar mass is then 204.221 grams per mole.
871 grams
The gram-atomic mass of potassium is 39.098. This number multiplied by 0.41 = 16 grams.
The formula of anhydrous calcium chloride is CaCl2, and its gram formula mass is 110.99. The gram atomic mass of calcium is 40.08. Therefore, the grams of calcium in 100 grams of calcium chloride is 100(40.08/110.99) or 36.11 grams, to the justified number of significant digits.
The molar mass of potassium chloride is 74,5513.
Balanced equation and potassium limits and drives the reaction.2K + Cl2 -> 2KCl6.75 grams K (1 mole K/39.10 grams)(2 mole KCl/2 mole K)(74.55 grams /1 mole KCl)= 12.9 grams potassium chloride produced==============================
What is the mass, in grams, of 2 × 1012 atoms of potassium?
The molar mass of anhydrous aluminum chloride is 133,34 grams.
1meq = 74.5 mg 10meq = 745mg ( or 0.745grams) hope to have answered the question.
the solubility of potassium nitrate in 70 degreesCelsius water is about 134 g KNO3 per 100 g water
On heating potassium chlorate decomposes on potassium chloride and oxygen. 2KClO3------>2KCl+3O2 9.8g of KClO3 are heated. Calculate a. the mass of KCl formed. b. the mass and volume, at (s.t.p) of O2 formed.
Every atom of potassium has a mass of 39 amu. Each mole of potassium has a mass of 39 grams.

That depends on how much solution you have.
