To calculate the chloride concentration after mixing, we first need to figure out what is the limiting reactant, the potassium chloride or the silver nitrate.
00:10
We'll start with our 0 .306 grams potassium chloride and see how many moles of product, in this case the precipitate silver chloride can be produced.
00:21
We'll convert the grams potassium chloride into moles by dividing by the molar mass.
00:26
Once we have moles silver chloride, we can convert it into, sorry, potassium, calcium chloride, we can convert it into silver chloride with the one -to -one mole relationship.
00:39
We'd do a similar calculation with the 250 milliliters of 24 millimolar silver nitrate.
00:46
We'll start with our 250 milliliters, divide by a thousand to get liters, and then convert the liters into moles, recognizing 24 millimolar is 24 .0 times 10 to negative 3 moles per liter.
01:03
Once we have a mole silver nitrate, we use the one -to -one mole relationship to get moles silver chloride.
01:11
And if all of the potassium chloride is consumed, we would produce 0 .00410 moles of silver chloride.
01:21
And if all of the silver nitrate is consumed, we would produce 0 .006 .00 moles of silver chloride...
