How many grams of NaCl are in 3.25 moles of NaCl?

The molecular weight of sodium (Na) is 22.99 grams. The molecular weight of chlorine (Cl) is 35.45 grams. Therefore, there are 58.44 grams in 1 mole of NaCl. So, in 3.25 moles of NaCl, there are 58.44 gr x 3.25 = 189.93 grams.


How many grams are in 145 moles of NaCl?

Every mol of NaCl contains a mol of Na, weighting 23 grams, and a mol of Cl, weighing 35.5 grams. So, every mol of NaCl weights 58,5 (=23+35.5) grams. Therefore, 145 moles of NaCl weights 8482.5 grams.


How many moles in 29.22g of sodium chloride?

In 1 mol of NaCl there is 58.44 grams. ( 22.99 grams of Na + 35.45 grams of Cl). Using stoichiometry, you cancel the grams by taking 29.22 grams/58.44 grams. So 0.50 moles of NaCl


How many moles are in 5.6 grams of Na?

how many moles are in 5.6 grams of Na?


How many moles are in 13g NaCl?

1 mole NaCl = 58.442g NaCl (the atomic weight of Na and Cl in grams) 13g NaCl x (1mol NaCl/58.442g NaCl) = 0.22mol NaCl


What is the molarity of 9 g of Na Cl in 1 L of solution?

Molarity = moles of solute/Liters of solution Find moles NaCl 9 grams NaCl (1 mole NaCl/58.44 grams) = 0.154 moles NaCl Molarity = 0.154 moles NaCl/1 Liter = 0.2 M sodium chloride -------------------------------


Calculate the number of Sodium in grams in 7.6 grams of NaCl?

(7.6 g NaCl) (moles NaCl/58.44 g NaCl) (1 mole Na/1 mole NaCl) ( 22.99 g Na/mole Na) = 2.989 g Na or 3.0 g Na (significant figures) Steps: 1. Change everything to moles: use molar mass/molecular of NaCl 2. Find the molar ratio: since there are 1 Na in every NaCl, then the ratio of NaCl to Na is 1:1 3. Change moles back to grams: use the molar mass/molecular weight of Na 4. Watch out for significant figures! I hope this is right


How many moles in 2.4 grams of NaCl?

1 mol of NaCl is 58.5 grams (Ar of Na is 23, and Ar of Cl is 35.5). Now we set up an equation1 mol : x = 58.5 g : 2.4 gx = 0.0410 molSo, 2.4 grams of NaCl has 0.0410 moles of NaCl.?


How many moles of Na are in 15 g of NaCl?

Molar Mass NaCl is 58.5g, 39.3% Na (5.90g), Molar Mass Na is 23.0g, 5.90/23.0 = 0.256 moles


How do you calculate the molarity of the solution of 17.52 grams of Na Cl in a total volume of 2000 ml of solution?

Need moles NaCl first. 17.52 grams NaCl (1 mole NaCl/58.44 grams) = 0.29979 moles NaCl =====================Now. Molarity = moles of solute/Liters of solution ( 2000 ml = 2 Liters ) Molarity = 0.29979 mole NaCl/2 Liters = 0.1499 M NaCl ----------------------


How many moles are in 1 kg of NaCl?

For this conversion you need the atomic masses of the two elements to find the molecular mass of the NaCl.Na: 23.0Cl: 35.5NaCl: 58.5Then, you follow the formula:Mass in grams ÷ Molecular mass = Mass in moles1000 g NaCl ÷ 58.5 = 17.1 moles NaCl


How many moles of ions are in 2.5 mol of NaCl?

Based on the stoichiometry of NaCl, for every one mole of NaCl there is one mole of Na+ and one mole of Cl-. Therefore, there are 2.5 moles Na+ and 2.5 moles Cl-, totaling 5 moles of ions altogether.


How many moles of ions are in 1.5 mol of NaCl?

Based on the stoichiometry of NaCl, for every one mole of NaCl there is one mole of Na+ and one mole of Cl-. Therefore, there are 1.5 moles Na+ and 1.5 moles Cl-, totaling 3 moles of ions altogether



What is the mass of 2 moles of sodium chloride?

2 * [(Na=23) + (Cl=35.5)] = 117 grams NaCl


How many grams of Na are there in 2.04 moles of Na?

The atomic weight of Na is 23.0 g/molTo convert moles to grams:grams Na = 2.04 mol Na23.0 g = 46.9 g Na1 molMultiply by grams per mole. Moles cancel out.


How many moles of sodium are in 4.25 moles of NaCl?

In each formula unit of NaCl there is one Na+ ion. Therefore, amount of sodium ions = amount of NaCl = 4.25mol


The sterile solution used to rinse contact lenses can be made by dissolving 400 mg of NaCl in sterile water and diluting to 100 mL. what is the molarity of this solution?

First, find the moles of NaCl. Because you have 400 milligrams of NaCl convert to grams by dividing 1000mg. 400mg/1000mg = 0.400 grams of NaCl. Now we need to convert to moles. For every mole of NaCl there is 58.44 grams. (22.99g Na + 35.45 g Cl) so using stoichiometry (grams cancel) I get .0068 moles of NaCl. Conver 100 mL to L by dividing by 1000mL. Therefore there is .001 L in the solution. Molarity is moles per Liter. So 0.0068 mols of NaCl / 0.001 L = 6.84 M


How mny moles are in 23.34 of NaCl?

I'm going to assume that you mean 23.34g of NaCl. 1 mole NaCl = 58.442g NaCl (the atomic weight of Na and Cl in grams) 23.34g NaCl x (1mol NaCl/58.442g NaCl) = 0.3994mol NaCl


How many moles are in 11.5 Grams of Na?

For this you need the atomic mass of Na. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.11.5 grams Na / (23.0 grams) = .500 moles Na


How many moles of sodium chloride are there in 238 grams of sodium chloride?

1 mole of NaCl: Na = 1 * 22.99 g = 22.99 g Cl = 1* 35.45 g = 35.45 g Total = 58.44 g 238 g NaCl * (1 mol NaCl/58.44 g NaCl) = 4.07 mol NaCl There are approximately 4.1 moles in 238 grams of sodium chloride.


How many grams of soduim are in 3 moles of soduim carbonate to the nearest gram?

3 moles Na2CO3 (2moles Na/1mole Na2CO3)(22.99 grams Na/1 mole Na) = 138 grams of sodium


How many moles of Na are there in 5 moles NaCl?

There are 5 formula masses of Na in 5 formula masses of NaCl, as indicated by the fact that the symbol for sodium has no explicit subscript in the formula of NaCl. Neither sodium nor sodium chloride has moles in the strictest sense, since neither of them is covalently bonded.


How many moles are in 17.5 grams of sodium?

For this you need the atomic mass of Na. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.17.5 grams Na / (23.0 grams) = .761 moles Na
