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 ppm of Na in 100 ppm NaCl?
(22.99 g/mol Na / 58.43 g/mol NaCl ) x 100 ppm NaCl= 39.35 ppm 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
How many Na ions are in 4.2 g of NaCl?
2
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.
How much Na is needed to produce a 5 grams of table salt?
5 grams of table salt is 5 grams of NaCl. NaCl has a molar mass of 58.443 grams/mol, so 5 grams would be .0855 mol NaCl. In one mole of NaCl there is one mole of Na, so there would be .0855 mol Na, or 5.235 * 1022 atoms Na.
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 sodium ions can be found in 145g of NaCl?
145 grams NaCl (1 mole NaCl/58.44 grams)(1 mole Na +/1 mole NaCl)(6.022 X 1023/1 mole Na +) = 1.49 X 1024 ions of sodium =====================
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
What is weight of na in 348 grams of nacl?
[348 (g NACl)] * [23 (g/mol Na)] * [1 (mol NaCl/mol Na)] / [58.5 (g/mol NaCl)] = [348*23/58.5] = 136.8 = 137 g Na
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 grams of NaCl are in 1.92 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.
What is the number of grams of sodium in 8.0g of NaCl?
Amount of NaCl = 8.0/58.5 = 0.137mol In each unit of NaCl there is one Na+ ion. Mass of Na = 0.137 x 23.0 = 3.15g
If you weighed 79.00 grams of NaCl how many mole of NaCl did you weigh?
I'll see if I can type it out for you.. 79g NaCl x (1 mol NaCl)/(58.44g NaCl) = 1.35 mol NaCl 1 mol NaCl = 58.44g (because Na is 22.99g and Cl is 35.45g)
How many moles in 5 grams of NaCl?
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
Calculate the grams of sodium in 7.6 grams of NaCl?
NaCl has a molar mass of 22,989 769 28 + 35,453 = 58,442 769 28 g Na has an atomic weight of 22,989 769 28 g. % Na = 22,989 769 28 ÷ 58,442 769 28 = 39,337 Mass of Na in 7,6 grams of NaCl = 0,39337 x 7,6 g = 2,99 g
How many grams are in 2.5 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.
