Anhydrous conditions are vital for a successful Grignard synthesis. To demonstrate this point calculate the mass of the water it would take to destroy the phenylmagnesium bromide you will synthesize. What is he volume of this amount of water?

-How exactly do you do this?

What compound are you trying to make?

I would write an equation, something like this:
RMgX + HOH ==> RH + MgXOH
I'm assuming you aren't trying t make the RH compound but this is one method for preparing alkanes or ArH
Then use freshman stoichiometry to calculate the mass of water from the reaction that will react with the amount of the phenylMg Br.

To calculate the mass of water required to destroy the phenylmagnesium bromide, we need to determine the stoichiometric ratio between the two compounds.

The balanced chemical equation for the reaction between phenylmagnesium bromide (C6H5MgBr) and water (H2O) is:

C6H5MgBr + 2H2O → C6H6 + Mg(OH)Br

From the equation, we can see that for every mole of phenylmagnesium bromide, we need 2 moles of water.

Step 1: Calculate the molar mass of phenylmagnesium bromide (C6H5MgBr):
C6H5 = 6(12.01) + 5(1.01) = 78.11 g/mol
Mg = 24.31 g/mol
Br = 79.90 g/mol

Molar mass of phenylmagnesium bromide (C6H5MgBr) = 78.11 + 24.31 + 79.90 = 182.32 g/mol

Step 2: Calculate the molar mass of water (H2O):
H2 = 2(1.01) = 2.02 g/mol
O = 16.00 g/mol

Molar mass of water (H2O) = 2.02 + 16.00 = 18.02 g/mol

Step 3: Calculate the stoichiometric ratio:
1 mole of phenylmagnesium bromide reacts with 2 moles of water.

Step 4: Calculate the mass of water:
To calculate the mass of water, we can use the molar mass and stoichiometric ratio.

Mass of water = (molar mass of water / molar mass of phenylmagnesium bromide) × mass of phenylmagnesium bromide

Mass of water = (18.02 g/mol / 182.32 g/mol) × mass of phenylmagnesium bromide

Step 5: Determine the value of the mass of phenylmagnesium bromide synthesized in your Grignard reaction.

Once you have the mass of phenylmagnesium bromide, substitute it into the equation to calculate the mass of water required.

Step 6: Convert the mass of water to volume (assuming water density is 1 g/mL):

Volume of water = Mass of water (in grams) / Density of water (1 g/mL)

By following these steps, you can calculate the mass of water required to destroy the phenylmagnesium bromide and then convert it to volume.

To calculate the mass of water required to destroy the phenylmagnesium bromide, we need to know the molar mass of phenylmagnesium bromide and the stoichiometric ratio between phenylmagnesium bromide and water.

The molar mass of phenylmagnesium bromide is the sum of the molar masses of its constituent elements. The formula for phenylmagnesium bromide is C6H5MgBr. Hence, the molar mass can be calculated as follows:

Molar mass of C = 12.01 g/mol
Molar mass of H = 1.01 g/mol
Molar mass of Mg = 24.31 g/mol
Molar mass of Br = 79.90 g/mol

Molar mass of phenylmagnesium bromide:
(6 * molar mass of C) + (5 * molar mass of H) + molar mass of Mg + molar mass of Br =
(6 * 12.01) + (5 * 1.01) + 24.31 + 79.90 = 161.20 g/mol

Now, to determine the stoichiometric ratio between phenylmagnesium bromide and water, we need to refer to the balanced equation of the reaction. The reaction between phenylmagnesium bromide and water is as follows:

C6H5MgBr + H2O → C6H6 + Mg(OH)Br

From the balanced equation, we can see that one mole of phenylmagnesium bromide reacts with one mole of water. Therefore, the stoichiometric ratio is 1:1.

Knowing the molar mass of phenylmagnesium bromide and the stoichiometric ratio, we can now calculate the mass of water required to destroy the phenylmagnesium bromide.

Mass of water = (mass of phenylmagnesium bromide / molar mass of phenylmagnesium bromide) * molar mass of water

Since the question asks for the volume of water, we also need to consider the density of water, which is approximately 1 g/mL.

Volume of water = mass of water / density of water

To finalize the calculation, we need to know the mass of the phenylmagnesium bromide used in the synthesis. Once given, plug the value into the formula to find the mass and volume of water required.
