Answer:
V = 177.4 L.
Explanation:
Hello there!
In this case, since this gas can be assumed as ideal due to the given data, we can use the following equation:

Thus, by solving for volume we obtain:

So we can plug in the temperature in Kelvins (537 K), the pressure in atmospheres (0.404 atm) and the molar mass (54 g/mol) to obtain:

Best regards!

Explanation:
The steps involved in predicting the structure of the alkyl bromide compound are outlined below.
1) An examination of the product shows that the product could only be formed by a substitution reaction.
2) The structure of the alkyl bromide compound can be then predicted by replacing the methoxide group in the product after the substitution of bromine atom. This is because the methoxide ion acts as a strong nucleophile.
Therefore, by consideration the reaction mechanisms of reactions 1 and 2, it can be predicted that the structure of the alkyl bromide compound is
--
--
--Br--
. A pictorial diagram of the alkyl bromide compound is also attached.
The volume of cylinder is 100 mL, inner diameter is 3.2 cm thus, radius will be:

Volume of layer formed=
...... (1)
Volume of layer is also equal to sum of volume of gasoline and water.
Density of gasoline is
and mass is 34 g thus, volume of gasoline will be:

Now, density of water is
and mass is 34 g thus, volume of water will be:

Adding both the volumes, volume of layer will be:

Putting the values in equation (1) to solve for height of the layer,

Thus, height of layer is 10.25 cm
