This mass is 72,02 g.
To determine the number of formula units in 0.0482 mol of sodium sulfate, you first need to find the molar mass of sodium sulfate (Na2SO4). The molar mass of Na2SO4 is approximately 142.04 g/mol. Then, divide the given amount of moles by the molar mass to find the number of formula units. In this case, there are approximately 3.39 x 10^22 formula units in 0.0482 mol of sodium sulfate.

There are four chlorine atoms in two calcium chloride formula units (CaCl2) because each formula unit contains two chlorine atoms.
The answer is 2,09 moles.
A formula unit can also be referred to a mole unit. A mole or formula unit is the smallest amount of a substance that contains all the atoms or elements of a substance.
There are a total of 12 oxygen atoms in two calcium carbonate formula units. Each formula unit of calcium carbonate (CaCO3) contains 3 oxygen atoms, so for two formula units, there would be 6 oxygen atoms in each unit, totaling 12 oxygen atoms.
A mole of substance contains Avogadros number (6.022 X 1023) formula units or molecules). 5.33 mol will contain 5.33 X 6.022 X1023 = 3.209 X1024
There are 14 chlorine atoms in seven sodium chloride formula units. This is because each sodium chloride formula unit contains one chlorine atom, so in seven units there are 7 x 1 = 7 chlorine atoms.
Each formula unit of Fe2(C2O4)3 contains 15 atoms (2 Fe atoms, 6 C atoms, and 7 O atoms). Therefore, 5 formula units would contain a total of 75 atoms (5 formula units x 15 atoms per formula unit).
To find the number of moles, first determine the number of formula units in one mole of NaCl. One mole of NaCl contains Avogadro's number (6.022 x 10^23) of formula units. Therefore, 4.816 x 10^24 formula units of NaCl is equal to 8 moles.
