A solution is made by adding 27 g of barium chloride into 74 g of water. What is the mass percentage of this barium chloride in this solution, to the units place?

27 %

Explanation:

Step 1: Given data

Step 2: Calculate the mass of the solution

The mass of the solution is equal to the sum of the mass of the solute and the mass of the solvent.

m = 27 g + 74 g = 101 g

Step 3: Calculate the mass percentage of this barium chloride in this solution

We will use the following expression.

%m/m = mass of barium chloride / mass of solution × 100%

%m/m = 27 g / 101 g × 100%

%m/m = 27 %

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it
