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?

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)

A student placed 12.0 g of glucose (C6H12O6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100. mL mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 20.0 mL sample of this glucose solution was diluted to 0.500 L. How many grams of glucose are in 100. mL of the final solution? Express your answer to three...

A student placed 14.5g of glucose (C6H12O6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100mL mark on the flask was reached. The flask was then shaken until the solution was uniform. A 40mL sample of this glucose solution was diluted to 0.500L. How many grams of glucose are in 100mL of the final solution?

A compound with molecular mass = 292.16 g/mol was dissolved in a 5.000 mL volumetric flask. A 1.000 mL aliquot was withdrawn, placed in a 10.000 mL flask and diluted to volume. The apparent absorbance of the diluted solution at 340 nm was 0.827 in a 1.000 cm cuvette. To check for a possible stray light effect, this sample was diluted by exactly a factor of 2; the apparent absorbance was now 0.421. A reagent blank showed negligible absorbance. The...
