Use stoichiometry. 3.5g-> moles 22.99+16+1.0079=39.99 Now 3.5/39.99 = .088 moles of NaOH Now you can use avagadros number 6.022x10^23 .088 moles -> formula units .088/6.022x10^23 You should end up with 1.46x10-25 formula units. Yeah, I know, Chem sucks huh?
1 mole NaCl = 58.443g NaCl = 6.022 x 1023 formula units NaCl 3 x 1025 formula units NaCl x 1mol NaCl/6.022 x 1023 formula units NaCl x 58.443g NaCl/mol NaCl = 2911g NaCl = 3000g NaCl (rounded to 1 significant figure)
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams38.0 grams NaCl / (58.5 grams) = .650 moles NaCl
Sodium chloride is an ionic crystalline salt, and does not form molecules. One unit of sodium chloride is called a functional unit. It is the lowest whole number ratio of ions represented in an ionic compound. 1 mole = 6.022 x 1023 formula units of NaCl 3 moles NaCl x 6.022 x 1023 formula units/mole = 1.8 x 1024 formula units of NaCl

The maximum number of formula units of NaCl in one mole is 6.022 x 10^23, which is Avogadro's number. This means that in one mole of NaCl, there are 6.022 x 10^23 formula units of NaCl.
The number of formula units of NaCl is 11335.10e17.
To find the number of moles in 2.9 x 10^21 formula units of NaCl, you first need to determine the number of moles in 1 formula unit. As NaCl contains one Na+ ion and one Cl- ion, there is 1 mole of NaCl in 2 moles of ions. Then, you can calculate the number of moles in 2.9 x 10^21 formula units by dividing this number by Avogadro's number (6.022 x 10^23).
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
To find the number of moles in 8.4 x 10^23 formula units of NaCl, you need to convert formula units to moles. Since 1 mole of any substance contains Avogadro's number of particles (6.022 x 10^23), you would divide the number of formula units by Avogadro's number to get the answer. So, 8.4 x 10^23 formula units of NaCl is equal to 1.4 moles of NaCl.
How many grams of NaCl are present in 8.39x10^22 formula units of NaCl?

There are approximately 5.17 x 10^20 formula units of NaCl in 8.56 x 10^-3 mol of NaCl. This is found by multiplying Avogadro's number (6.022 x 10^23) by the number of moles given.
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58.5 grams38.0 grams NaCl / (58.5 grams) = .650 moles NaCl
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.
(2.3 x 10^23) / (6.02 x 10^23) =0.38 moles
