two methods were described for determining the volume of the flask used for the molar mass determination. Which method will give a more precise determination of the volume.

Precision depends on the ability of the method to reproduce the same or similar result in a measurement. The methods that after several measurements of the same observation produced the closest values between them is going to be the more precise.
Ej:
Method A: 3.0 L, 3.1L, 2.9L
Method B: 3.0 L, 4.1L, 1.9L
Method A will be more precise than Method B

Two methods were described for determining the volume of the flask used for the molar mass determination. The method that will give you a more precise determination of the volume is the ideal gas equation.

The Ideal gas equation will be more precise in the determination of the volume because it takes in the scenario for normalization of all measured quantities.

From the ideal gas equation:

PV = nRT

[tex]\mathbf{n = \dfrac{PV}{RT}}[/tex]

Where;

number of moles
P = pressure
V = volume
R = rate (constant)
T = temperature

Therefore, the method that will give you a more precise determination of the volume is the ideal gas equation.
