Solution: Let x - volume of the concentrated solution (in ml), then: 12.0 ∙ x = 0.369 ∙ 150 Solving: x = (0.369 ∙ 150) / 12.0 = 4.61 ml Answer: 4.61 ml

A concentrated solution of HCl has a molarity of 10.0 M. You add 23.50 mL to a flask and then dilute with water. The mass of the final solution is 125.0 g. What is the mass percent of HCl ?

Mass percent essentially means g of HCl/total grams of solution (x100%). So, in this problem we already know the total mass = 125.0 g. If we can find the mass...

250mL of a solution of HNO3 0.02mol/L are mixed with 150mL of a solution of NaOH 0.1mol/L. 1. Write the equation of the reaction. 2. Calculate the pH of the final mixture.

1. HNO3 + 2NaOH ->> NH3 + H2O + Na22. Molar Mass of HNO3 = 63.01250/63.01= 3.97 molesMolar Mass of NaOH = 37.999= 15/37.999= 0.395= 3.97/0.395 = 10.1Log 10.1PH=...

If you dilute 20.0 L of a 4.5 M solution to make 150 L of solution, what is the molarity of the dilute solution?

The amount of moles in the initial and resulting solutions is constant. V1 ·CM1 = V2·CM2 20 · 4.5 = 150 · CM2 CM2 = (20·4.5)/150 = 0.6 M
