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 many Na ions are in 4.2 g of NaCl?

How many atoms of sodium are in 2.35 mol of NaCl?
There are 1.41 e24 atoms of Na in 2.35 mol of NaCl.
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 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.
Is 100 ppm solution of NaCl means 100 ppm of Na?
No 100 ppm of NaCl = 100 mg NaCl/1 L = 67,87 ppm (67,87 mg/L) of Na
Preparation of 1000ppm of standard Sodium solution from NaCl?
1 mg/l = 1ppm1 g/l = 1000 ppmNaCl ----------------> Na+ + Cl-58.5 g NaCl gives 22.989 g Na+(58.5 / 22.989) = 2.545 g of NaCl is required to give 1 g of Na+When 2.545 g of NaCl is dissolved in 1 liter water will yield 1000 ppm of Na+ in NaCl solution.
What happens with dissociation in NaCl?
The equation is: NaCl----------Na++ Cl-
What is the cation for NaCl?
The cation, or positively charged ion, in NaCl is Na+.
What is the dissocociation of NaCl to Na Cl?
NaCl---------------→Na+ + Cl-
How many teaspoons of one gram of salt?
1 teaspoon of salt (NaCL) = 6 grams of NaCL or 2,360 mg of sodium (Na). (Na molecular wt is 23, Cl is 35.5, so NaCl is 58.5, so Na is 40 % times grams of wt of NaCl.) So 1 gram NaCl X 1 tsp/6 g NaCl = 0.16667 tsp NaCl or if you want Sodium ( how salt is expressed on food labels) then 1 gram of Na X 1 tsp NaCl/2.360 gram Na = 0.42 tsp Na.
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
Na+ and Cl- are ions formed from?
Na+ + Cl- --> NaCl NaCl = salt.
How many Na ions are in 4.2 g of NaCl?
2
How many atoms of sodium Na are there in the formula for table salt NaCl?
NaCl is one atom of Na and one atom of Cl. Therefore, each molecule of NaCl has 2 atoms each, combined.
What is the dissociation equation for NaCl?
NaCl --> Na+ + Cl- You could write water on either side I suppose, but it is negligible. I've also seen H2O written over the arrow.
Ions formed from Na plus and Cl- are?
Na+ + Cl- --> NaCl NaCl = salt.
