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 of sodium are in 200ml of 0.45 percent 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 = 39,337 200 mL of 0,45 % sodium chloride contain 0,9 g NaCl. Mass of Na in 0,9 grams of NaCl = 0,39337 x 0,9 g = 0,354 g
How do you make 1000ppm standard of Na using the salt NaCl?
To make a 1000 ppm Na standard solution using NaCl, you would dissolve 0.0585 grams of NaCl (molecular weight of NaCl = 58.44 g/mol) in 1 liter of water. This would give you a solution with a concentration of 1000 ppm Na.
A mixture of NaCl and NaBr has a mass of 2.03 g and is found to contain 0.76 grams of Na What is the mass of NaBr in the mixture?
To find the mass of NaBr in the mixture, we first calculate the mass of Na in NaCl and NaBr combined, which is 0.76 g. Since NaCl contains one Na atom and NaBr contains one Na atom, this entire mass comes from Na in NaCl and NaBr. Therefore, the mass of NaCl is 0.76 g and the remaining mass of the mixture (2.03 g - 0.76 g = 1.27 g) is due to NaBr.
What is the number of grams of sodium in 8.0g of NaCl?
In NaCl, the molar mass of Na is 22.99 g/mol and Cl is 35.45 g/mol. Therefore, the molar mass of NaCl is 58.44 g/mol. Given 8.0g of NaCl, the mass is distributed between Na and Cl in a 1:1 ratio. Thus, there are 3.5g of Na in 8.0g of NaCl.
4.1 grams NaCl is how many grams of Na?
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 4,1 grams of NaCl = 0,39337 x 4,1 g = 1, 613 g
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
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 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 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 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.
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 grams of sodium are in 200ml of 0.45 percent 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 = 39,337 200 mL of 0,45 % sodium chloride contain 0,9 g NaCl. Mass of Na in 0,9 grams of NaCl = 0,39337 x 0,9 g = 0,354 g
How do you make 1000ppm standard of Na using the salt NaCl?
To make a 1000 ppm Na standard solution using NaCl, you would dissolve 0.0585 grams of NaCl (molecular weight of NaCl = 58.44 g/mol) in 1 liter of water. This would give you a solution with a concentration of 1000 ppm 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 =====================
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.
