K2O is potassium oxide. Formula mass = 94g
32.6 g x 1 FU/94 g = 0.35 formula units
The mass is 2.86 grams but the weight will be 0.028 Newtons.
It depends on the substance and its molar mass.In order to convert from grams to formula units, you must first convert grams to moles, then moles to formula units (grams --> moles --> formula units).1. Divide the mass (g) of the given substance by the substance's molar mass.2. Multiply the number of moles found in Step 1 (above) by Avogadro's number (6.022 x 1023).---- Mass substance ----- X 6.022 x 1023 formula unitsMolar mass substanceCONVERSION FACTORMass (g) substance x 1 mol substance ------- x ----- Avogadro's number/////////////////// molar mass (g) substance ------------ 1 mol substance
Okay, a mole of potassium perchlorate contains 6.02x1023 formula units of potassium perchlorate, but you're asking about individual atoms. So, let's look at the formula: KClO3. That's 1 potassium, 1 chlorine, and 3 oxygens, for a total of 5 atoms per formula unit. Now, multiple 5 by Avogadro's number above, to get 30.1x1023, which simplifies to 3.01x1024 atoms.
The common units for density is grams per liter. Density can be given in any units of mass per any unit of volume (i.e. kg per milliliters).
Hydronium ions have the formula H3O+

Assuming that the number "9.871023" would or should have been written as "9.87 X 1023" if the typographical resources to do so were available to the questioner: Avogadro's Number, which is the number of formula units in a mole of any material, is about 6.022 X 1023. The gram formula mass for aluminum oxide is 101.96. Therefore, the mass of the stated number of formula units of aluminum oxide is: 101.96(9.87/6.022) or about 164 grams, to the justified number of significant digits.

The answer is 32,4.10e23.
How many grams of NaCl are present in 8.39x10^22 formula units of NaCl?
The mass is 991,5 g.
The mass is 2.86 grams but the weight will be 0.028 Newtons.
A same number.
The number of formula units of NaCl is 11335.10e17.
2.159*10^-25
Na2O is sodium oxide. The 2 at the beginning means that there are two formula units of it.
