If potassium has a mass of 39.1 amu and chloride has a mass of 35.45 amu which is the mass of potassium chloride when these two ions are combined?
The molar mass of potassium chloride is 74,5513.
Chemical fomula of salt?
Lite salt is made from 50 percent potassium chloride or KCl. and 50 percent sodium chloride NaCl. Potassium chloride has a molar mass of 74.5513 g/mol.
What is the molar mass for potassium iodide?
The molar mass for potassium iodide is 166,0028.
A solution of scandium chloride was treated with silver nitrate The chlorine in the scandium compound was converted to silver chloride AgCl A 82.5 mg sample of scandium chloride gave 234.4 mg of si?
1. Find the molar mass of scandium chloride (ScCl3) 2. Then divide the atomic mass of scandium by the molar mass of scandium chloride. 3. Multiply by 100 to get the percentage. ** Do the same thing for chloride and dont forget to multiply the molar mass of chloride by 3
What mass of potassium benzoate trihydrate is needed to prepare one liter of a 0.125 molar solution of potassium benzoate?
From the definition of molar concentration, the required amount of solute for the solution specified is 0.125 moles. The gram formula mass for potassium benzoate trihydrate is 214.26. Therefore, the mass required is 0.125 X 214.26 or about 26.8 grams, to the justified number of significant digits.
If potassium has a mass of 39.1 amu and chloride has a mass of 35.45 amu which is the mass of potassium chloride when these two ions are combined?
The molar mass of potassium chloride is 74,5513.
A solution has a pH of 4.5 this solution is?
One such solution can be made by mixing 50 milliliters of 0.1 molar potassium hydrogen phthalate with 0.1 milliliter of 0.2 molar hydrochloric acid, then diluting this mixture to a total volume of 100 milliliters. This is from theHandbook of Chemistry and Physics, 66th Edition, page D-145. This is, of course, not the only correct answer to this question.
What is the molar heat of solution for ammonium nitrate and calcium chloride?
81.1 kj/mol
How would you make a 1.25 molar solution of potassium hydroxide?
The formula mass of KCl is 75.5 so when 94.375g of it are dissolved in i litre water the solution prepared is 1.25 molar
What is a solution whose pH is 4?
One such solution can be made by mixing 50 milliliters of 0.1 molar potassium hydrogen phthalate with 0.1 milliliter of 0.2 molar hydrochloric acid, then diluting this mixture to a total volume of 100 milliliters. This is from theHandbook of Chemistry and Physics, 66th Edition, page D-145. This is, of course, not the only correct answer to this question.
How many grams of magnessium chloride are in 1liter solution 2.5M?
Magnesium chloride has a molecular weight of 95.2, so 1 litre of 1 molar MgCl2 would have 95.2g. A 2.5 molar solution would have 2.5X95.2g per litre = 238grams
What is the molar concentration of K ions in a 0.0175 M solution of potassium phosphate?
0,052 moles
Chemical fomula of salt?
Lite salt is made from 50 percent potassium chloride or KCl. and 50 percent sodium chloride NaCl. Potassium chloride has a molar mass of 74.5513 g/mol.
What is the molarity of chloride ion in 100 ml of a 500 M barium chloride solution?
I assume you mean 0.5 molar, but I'll go with what I'm given. If you have 500 molar of barium chloride, you will have 1000 molar of chloride ions as there are 2 chlorides for every 1 molecule of barium chloride. Having the 100ml there is irrelevant as you are talking about concentration and didn't ask for moles.
How do you prepare the molar solution of K2Cr2O7?
Dissolve 294,185 g of potassium dichromate in 1L demineralized water.
How many moles of KCI would be dissolved in 4 liters of water to make a 2 Molar solution?
We need 8 moles potassium chloride.
What is the molar mass for potassium iodide?
The molar mass for potassium iodide is 166,0028.
