Question

In a Laboratory you dissolve 13.8 nickel bromide in a volumetric flask and add water to a total volume of 375 mL what is the molarity of the solution?

In the laboratory a student who needs 19.1 mL of 11.2 M nitric acid solution to total volume of 100.0 mL what is the concentration of the diluted solution ?
How many milliliters of 6.83 M nitric acid solution should be used to prepare 3.50 L of .100 M HNO3?

Explanation / Answer

Ans 1 :

Molarity = no. of moles of solute / volume of solution in L

13.8 g of nickel bromide = 13.8 / 218.53 = 0.063 moles

M = 0.063 / 0.375

= 0.168 M

So the molarity of the solution will be 0.168 moles.
