I was given several equations to use for this assignment so, before assuming that I got this right, I wanted to check my answers. I don't think I have them done correctly...(adsbygoogle = window.adsbygoogle || []).push({});

What is the molarity of a solution of silver perchlorate, AgClO4, if 3.2 moles of silver perchlorate are dissolved in 1.5 liters of water?

molarity = moles/ volume

molarity = 3.2/1.5

molarity = 2.13

How many moles of potassium iodide, KI, must be used to make 1.500 L of a 0.2 M solution?

moles = 1.500/0.2

moles = 7.5

What is the molarity of the solution produced when 151 g of sodium chloride, NaCl, is dissolved in enough water to prepare .375 L of solution?

molarity = grams/molar mass

molarity = 151/.375

molarity = 402.6

How many grams of potassium chloride, KCl, are needed to prepare 0.630 L of a 2.50 M solution of potassium chloride?

(2.50)(.630) = x/74.6

1.575= 74.6x

.021 = x

.021 grams
