1.25-g of BaCl2 is placed in a 4.000 L volumetric flask. Then the volumetric flask is filled with D.I. water to the 4.000 L mark. All the BaCl2 goes into the solution. Assume the density of the solution is 1.00 g/mL.

What is the mass/mass (m/m) % and the mass/volume (m/v) of the solution?

Solutions

Expert Solution

Given:

Volume: 4.00 L

Density of the solution: 1.00 g/mL

Formula to be used:

Density of a solution = mass of the solution/volume of the solution

Density and volume has been given.

So, mass of the solution = Density of a solution* volume of the solution

= 1.00 g/mL* 4000 mL (4.00 L)

M= 4000 g

mass/mass % of the solution= mass of the solution/ mass of the solution

= (4000/4000)*100

= 100%

mass/volume (m/v) = mass of the solution/ volume of the solution

= 4000 g/4000 mL

= 1 g/mL (i.e., density)
