If $30.0 \mathrm{mL}$ of $0.150 \mathrm{M} \mathrm{CaCl}_{2}$ is added to $15.0 \mathrm{mL}$ of$0.100 M \mathrm{AgNO}_{3},$ what is the mass in grams of $\mathrm{AgCl}$ precipitate?

$0.215 \mathrm{g} \mathrm{AgCl}$ is formed

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, question 81 question 81, give 2 sets of solution, 30 m, calcium chloride, 115 and another 115 munim, and we need to find a mass of civil civil recipetal and before we do with this subtraction, we have to fight which are a limiting reactant, and you guys Should calculate more of the system first because we started try the equation: okay, we remember what this formula m go: n over v, o n o b equal, but on this formula, quick and calculi, calcium, glorie and silver nitrate. Remember you have to convert a milliliter 2 liter before we do it. Why? Because polarity is more over later, not more of a milliliters and after we calculate we got the mass of calcium lowrie amount and the amount of silver nitrate. Then we write equation. We write equation, so we have to find a more radio of the substance in the equation from this small radio. We should find which 1 limiting reactant- and you can tell here. If we have 2 miles of sienite, we will get only 1, calcium chloride, and now, if we have 1.5 camp, the neat 3 more of silver nitrate, so we only got 7.5 terms: the negative 4 calcium lowrie. So this is the limiting. So that's why? Because coireactant react in the question less than the amount of calcium lori they gave us so calcium lora is a set reaction and suiting reaction. We calculate we also calculates as of silver chloride, 2 and we have the same ammonia and how you can get this number. You have to do some wit here base in the equation. Okay, make a lot, and now we have, they give us 1.5 times tenet, more silver, nitrate and this equation. We had 2 calcium lori. Now it should be late like this tuma, calcium chloride, and we have the pipe 2 man. We do conversion we go cross. Okay, we got this proportional radio, so we will have 7.50 times 10, it 4 more and the same. If we want to a silver night driven, we do the same way and now and the y or divided by 1, more silver nitrate and we got the same amount. And now we just have to find the mass of the silver chloride recipitaeg to be game. Silver nitre chloride, time molar mass we do many times before and what can we have? We should have .50 time 10 negative 3. More and time for. Let me calculate this tollrso. We should have let's see 215 time- 10 negative. I forgot you, but this 1 time 43232 gram over mar of silver, nitrate, okay, and so that this 1 should be equal and we have about a boy 215 grams.
