Complete Question

A chemist prepares a solution of barium chlorate BaClO32 by measuring out 42.g of barium chlorate into a 500.mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in /molL of the chemist's barium chlorate solution. Be sure your answer has the correct number of significant digits.

The concentration is

Explanation:

   From the question we told that

     The mass of is  

     The volume of the solution  

Now the number f moles of   in the solution is mathematically represented as

Where   is the molar mass of which a constant with a value

Thus

The concentration of  in the solution is mathematically evaluated as

substituting  values  

they both have a y in them
