If the density of methanol is 0.793 kg/L, what is its volume needed for making 2.5L of its 0.25M solution?

Step 2: estimating the volume of methanol required for the solution

Using the molarity formula, we can get the mass of methanol required for the solution as follows:

• Molarity = given mass/ molar mass x volume (L)
• 0.25 molL-1 = mass/ (32 g mol-1 x 2.5 L)
• Mass of methanol = 20 g = 0.20 Kg

Step 3: Volume of methanol Calculation Density is defined as the proportion of mass to volume.

As a result, the amount of methanol required can be calculated as follows:

• Volume = mass/density
• Volume = 0.2 Kg/ 0.793 Kg L-1
• Volume = 0.2522 L = 25.22 mL

Therefore, 25.22 mL is the amount of liquid required to make its 0.25 M solution in 2.5 L.

Summary:

If the density of methanol is 0.793 kg/L, what is its volume needed for making 2.5L of its 0.25M solution?

If methanol has a density of 0.793 kg/L, then 25.22 mL of methanol is required to make 2.5L of its 0.25M solution. The volume of methanol is defined as the ratio of mass by density in mL.
