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?
To calculate the number of formula units in 3.6 grams of NaCl, you first need to determine the molar mass of NaCl by adding the atomic masses of sodium (Na) and chlorine (Cl). Then, convert the grams of NaCl to moles using the molar mass. Finally, use Avogadro's number (6.022 x 10^23) to find the number of 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

How many grams of sodium chloride are in 3 x 10 to the 25 formula units of sodium chloride?
To calculate the grams of sodium chloride, you first need to determine the molar mass of NaCl, which is 58.44 g/mol. Then, multiply the molar mass by the number of formula units given (3 x 10^25) to get the total grams of sodium chloride.
How do I convert 38 grams of NaCl to moles and formula units?
To convert 38 grams of NaCl to moles, you first find the molar mass of NaCl (58.44 g/mol) and then divide the mass by the molar mass to get moles (38g / 58.44 g/mol = 0.651 moles). To convert moles to formula units, you multiply the number of moles by Avogadro's number (6.022 x 10^23 formula units/mol), giving you 3.92 x 10^23 formula units.
How many moles are in 20.0 grams of NaCl?
To find the number of moles in 20.0 grams of NaCl, first find the molar mass of NaCl, which is approximately 58.44 g/mol. Then, divide the given mass by the molar mass to get the number of moles. In this case, 20.0 grams of NaCl is about 0.342 moles.
How many grams of NaCl molecular weight 58.5 g mole -1 would you dissolve in water to make a 0.5M NaCl solution with 500 ml final volume?
You would need to dissolve 14.62 grams of NaCl in water to make a 0.5M NaCl solution with a final volume of 500 ml. This calculation is based on the formula: moles = Molarity x Volume (in liters), and then converting moles to grams using the molecular weight of NaCl.
How many grams are in 3.40 of sodium chloride NaCl?
There are 3.40 grams of sodium chloride (NaCl) in 3.40 grams.
How many grams of NaCl are present in 8.39x1022 formula units of NaCl?
How many grams of NaCl are present in 8.39x10^22 formula units of NaCl?
How many NaCl formula units make up 0.11 grams of salt crystals?
The number of formula units of NaCl is 11335.10e17.
How many formula units in 3.6 grams of NaCl?
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
How many grams of sodium chloride are in 3 x 10 to the 25 formula units of sodium chloride?
To calculate the grams of sodium chloride, you first need to determine the molar mass of NaCl, which is 58.44 g/mol. Then, multiply the molar mass by the number of formula units given (3 x 10^25) to get the total grams of sodium chloride.
How many ions are in 4.5 moles of NaCl?
4.5 moles NaCl = 4.5000000000001 formula units NaCl *******************2nd Opinion************* 4.5 moles of NaCl would contain 4.5 x (6.02 x 1023) formula units. = 2.7 x 1024 formula units
How do I convert 38 grams of NaCl to moles and formula units?
To convert 38 grams of NaCl to moles, you first find the molar mass of NaCl (58.44 g/mol) and then divide the mass by the molar mass to get moles (38g / 58.44 g/mol = 0.651 moles). To convert moles to formula units, you multiply the number of moles by Avogadro's number (6.022 x 10^23 formula units/mol), giving you 3.92 x 10^23 formula units.
How many formula units are in this same 0.665mol NaCl?
0,665 moles NaCl is equivalent to 38,86 g.
How many moles are in 2.9 x 1021 formula units of NaCl?
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).
What is the maximum number of formula units of NaCl in one mole?
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.
How many molecules of NaCl are in 20grams?
The answer is 4,328.1023formula units (not molecules).
How many moles are in 8.4 x 1023 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 NaCl formula units does it contain?
0,16 mg NaCl is equivalent to 2,7.10-5 mol.
