Frances wanted to prepare a 0.0285M standard solution of LiCl. She weighed out 27.5g of solid LiCl. She had plenty of water available. What volume of the solution was she able to prepare?

Answer 1

how many moles in 27.5g?
We only need .0285 moles/liter
so divide the # moles of salt by the molarity to get the volume.

Answer 2

Thank you so much for your help. Once I got the formula to convert grams to moles, this was a lot of help. But could you check my work for me? I converted the grams to moles and got 0.648737909 mol LiCl. Then I divided that by 0.0285M and got 22.76273365 L which I rounded to be 22.8 liters of LiCl.

Answer 3

So is 22.8 the correct answer?

Answer 4

I'm almost 100% sure it is.
