A $0.8870-\mathrm{g}$ sample of a mixture of $\mathrm{NaCl}$ and $\mathrm{KCl}$ is dissolved in water, and the solution is then treated with an excess of $\mathrm{AgNO}_{3}$ to yield $1.913 \mathrm{g}$ of $\mathrm{AgCl}$. Calculate the percent by mass of each compound in the mixture.

In chemistry, a solution is a homogeneous mixture composed of two or more substances. The term "solution" is also used to refer to the resultant mixture. The solution is usually a fluid. The particles of a solute are dispersed or dissolved in the solvent. The resulting solution is also called the solvent. The solvent is the continuous phase.

In chemistry, an ion is an atom or molecule that has a non-zero net electric charge. The name was coined by John Dalton for ions in 1808, and later expanded to include molecules in 1834.

Okay for the problem 140 point: first, we have to take this smile. There'S many wythoute this. This is what way we can solve so last sodium chloride had not and potassium chloride being more. So you get the reaction of the mixture with set silver nitrate, when it's essential, for nitrate, mean sodium chloride and potassium arite completely react with coventried, no more life, okay and then after we write equation, we have to find a more radioed ratan problem in the many Preproblem so now i do i thank you familiar with this with i get a mob. Nitride react precipitate the same for potassium chloride, potassium precipitate and now we know m equals more time all mass. That'S why mare of cibelchloride qamas of cibao callaides in the question a and b the first question, the second question: a plus b right, and thus we have- and we panthi form this formula. So we get 1431143.5 plus 13.5 b equals 1.913 gram, or this number the in the problem and that's the similar way we combat for the mass of mature, potassium lori and bosoms him for the maplin right and mass of that mass that i am for more observing Power so for this equation we have 58.8 and thin for 745 to 4.5 b, with u a and b a man, another units that is, though, that's much o a question of massinger, and now i have a sittamore equation: 1 and 21 right here, 1 in possible And b 2 for the mass of mature, i have this equation, so i thank you for me with his system and you you that you can i a and b after you get that means and your time for the the morin you get 8 power 381 and The same you capite mass of plasmoid, is that they will need to call the mass of potassa to be got only a percentage. So, after that, you get a percentage of certain chloride divided by the mass of the mixture you get 43.7705 percent and because they get only 2 into substance, so 1 gets percent. Already you can get another 1100 percent, another percent. You get a percent for potassium lollie, and here i have you see, maybe our answer a little different form unformed another professor, so here because i serve equal 1 to 8 north 5.5, sodium 23 potassium in that is a vertically okay.
