Answer:

250 ml

Explanation: I got it right on the lab.

The size of the volumetric flask that would you use to create a 1.25 M solution using 29.75 g of MgCl₂ is 250mL.

How do we calculate volume of the solution?

Volume (V) in liter of the solution will be calculated by using the molarity (M) formula as:

M = n/V, where

n is the moles of the solute and it will be calculated by using mass as:

n = W/M, where

W = given mass

M = molar mass

Moles of 29.75g of MgCl₂ = 29.75g / 95g/mol = 0.313 mol

Given that molarity of solution = 1.25M

On putting values on the equation of molarity we will get the value of volume as:

V = 0.313 / 1.25 =  0.2504 L = 250mL

For the preparation of 250 mL of MgCl₂ solution we required the volumetric flask of 250 mL.

Hence volumetric flask of 250mL is required.
