A chemist prepares a solution of barium chloride by measuring out of barium chloride into a volumetric flask and filling the flask to the mark with water. Calculate the concentration in of the chemist's barium chloride solution. Round your answer to significant digits.

The given question is incomplete. The complete question is:

A chemist prepares a solution of barium chloride by measuring out 110 g of barium chloride into a 440 ml volumetric flask and filling the flask to the mark with water. Calculate the concentration in mole per liter of the chemist's barium chloride solution. Round your answer to 3 significant digits.

Concentration of the chemist's barium chloride solution is 1.20 mol/L

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,

n = moles of solute

= volume of solution in L

moles of (solute) =

Now put all the given values in the formula of molality, we get

Therefore, the molarity of solution is 1.20 mol/L

a electronegativity decreases beacuse the size of nucleus is bigger.
