What is the concentration of febr3 in a solution prepared by dissolving 10.0 g of febr3 in enough water to make 275 ml of solution?

The correct answer is 0.1236 M.

Explanation:

What is the concentration of in a prepared solution by dissolving 10.0 g of insufficient water to obtain 275 mL of solution?

First, we must look for the molar mass of iron bromide (III).

Mm = 295.56 g/mol

Then, the amount of moles in 10 g is equal to:

n=

n= 0.034 mol

Now to know the molar concentration we have to divide the number of moles of the compound by the volume of the solution in liters:

Volume=

M=

M=0.1236

Have a nice day!

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
