6.89 mole
A mole is a unitless quantity, similar to a dozen but many orders of magnitude larger. In principle one could have a mole of donuts, but there isn't enough room on earth for them.
The answer is 32,4.10e23.
How many grams of NaCl are present in 8.39x10^22 formula units of NaCl?
The number of atoms in two formula units of potassium nitrate is 10.
The molar mass of silver nitrate is 169,87 g: approx. two formula units.
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.
I mol contains 6.023 x 10 e 23. So the answer is 6.89 times that, or 4.149847 x 10 e 24.
K2O is potassium oxide. Formula mass = 94g32.6 g x 1 FU/94 g = 0.35 formula units
K2O is potassium oxide. Formula mass = 94g32.6 g x 1 FU/94 g = 0.35 formula units
The answer is 32,4.10e23.
The answer is 5,21131981201352.10e23 formula units of silver nitrate.
A same number.
