how many grams per L in 0.1M EDTA solution?

 

i have forgotten most my organic chemistry stuff -.-"

im a bit rusty.. coudl someone show me the formula and how to work it out step by step please?

 

thank you in advance

Molarity is [math]\frac{\mbox{moles of solute}}{\mbox{liters of solution}}[/math].

 

So in your case, [math]0.1\mbox{M} = \frac{x \mbox{ moles}}{1 \mbox{ liter}}[/math]. That can tell you how many moles of EDTA are in one liter of solution, and then you just need to find the molar mass of EDTA.

so Molar mass = 292.24g/mol

 

Applied to the formula give =

 

0.1M = 292.24g/1L

 

therefore the answer would be:

 

292.24 grams per Litre?

 

Molarity is [math]\frac{\mbox{moles of solute}}{\mbox{liters of solution}}[/math].

 

So in your case, [math]0.1\mbox{M} = \frac{x \mbox{ moles}}{1 \mbox{ liter}}[/math]. That can tell you how many moles of EDTA are in one liter of solution, and then you just need to find the molar mass of EDTA.

No. You have 0.1 moles in one liter of solution: 0.1M means 0.1 moles per 1 liter. Molarity tells you how many moles there are in one liter of solution.

 

If you have 0.1 moles, and each mole ways 292.24g, how much do you have?

0.1*292.24 = 29.22grams?

Exactly.
