Réponse : The volume of 10 mmol of ethyl acetoacetate is approximately 1.28 ml. This calculation assumes a density of 1.02 g/ml for ethyl acetoacetate.
Explications :
To convert ethyl acetoacetate from mmol to ml, you'll need to know its molar mass and density. The molar mass of ethyl acetoacetate is approximately 130.14 g/mol. However, the density is needed to complete the conversion, as it will allow us to relate the mass to the volume.
The general steps for the conversion are:
Let's assume the density of ethyl acetoacetate is around 1.02 g/ml, which is a typical value for this compound. (Keep in mind that the actual density can vary slightly based on purity and environmental conditions)
First, calculate the mass in grams :
Mass = Moles x Molar Mass
Mass = 10 mmol x 130,14 g/mol
Since 1 mol = 1000 mmol, we need to adjust the moles :
Mass = 0,01 mol x 130,14 g/mol
Then, convert the mass to volume using the density :
Volume = [tex]\frac{Mass}{Density}[/tex]
The volume of 10 mmol of ethyl acetoacetate is approximately 1.28 ml. This calculation assumes a density of 1.02 g/ml for ethyl acetoacetate. Remember, this value might vary slightly depending on the specific conditions and purity of your sample.
