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 units
Molar mass substance
CONVERSION FACTOR
47.63g substance x 1 mol substance ---- x ----- Avogadro's number
///////////////////// molar mass (g) substance ////// 1 mol substance
1g=1000mg When converting units, put what kind of units you want (grams) on top, and what kind of units you have (mg) on bottom. so.. 500mg x (1g) = 0.5 grams 1000mg mg will cancel leaving your units in grams.

How many cubic units is a box that is three (3) units height, three (3) units wide, and two (2) units deep. The formula is height * width * length, so if you put the numbers from the above equation into the formula it turns out as 3 * 3 * 2 which equals 18.
A conversion is the change between two units (usually units of measurement). For example... if you have 2 kg and you want to find out how many grams are in it, you multiply by the amount of grams there are in ONE kilogram, 1000. Therefore, 2 times 1000 is 2000 grams.
Use this formula: ounces x 28.35 = grams
How many grams of NaCl are present in 8.39x10^22 formula units of NaCl?
The number of formula units of NaCl is 11335.10e17.
31,35 g in 3,23.1023 molecules (formula units).
42.394 grams.
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
This mass is 244,459.10e23 g.
molar mass of MgCl2= 95.2195.21/125.25=0.76 mole1 mole would have 6.02x1023 formula units so 0.76 moles would have0.76 x (6.02x1023)= 4.575x1023 formula units.
1 mole NaCl = 58.443g NaCl = 6.022 x 1023 formula units NaCl 3.6g NaCl x 1mol NaCl/58.443g NaCl x 6.022 x 1023 formula units NaCl/mol NaCl = 3.7 x 1022 formula units NaCl
By definition, Avogadro's Number is the number of molecules or formula units in the number of grams corresponding to the gram molecular weight or gram formula unit, and by experiment, Avogadro's Number is about 6.022 X 1023. Therefore, 7.75 X 1025 formula units contains (7.75 X 1025/6.022 X 1023) or 1.29 X 102 moles or formula units, to the justified number of significant digits.
# of units = 9.374/15 = 0.625 units
Magnesium chloride (MgCl2) has a molecular weight of 95.21 grams per mole. 11.6 grams of MgCl2 is therefore .122 moles.
