Question

1. Identify the solute in each of the following solutions by circling it. a 60.0 ml of ethyl alcobol and 30.0 ml. of methyl alcohol b. 55.0 ml. of water and 1.50 g of NaCI is the molarity of 0 500 L of NaOH solution if it contains 6.00 g of NaOH? Determine the quantities of solute and solution. Write the concentration expression. Substitute solute and solution quantities into the expression. a. b. c. 3. Calculate the molarity of a solution formed by taking 350 ml.of 2.25 M HCI and adding 420 ml. of water. Assume volumes are additive. a. Prepare a table of the concentrations and volumes of the solutions. b. Rearrange the dilution expression to solve for the unknown quantity c. Substitute the known quantities into the dilution expression and solve.

Explanation / Answer

Ans 1 :

The solution is made up of two components : solute and solvent.

The substance which is in lesser quantity is called as solute , and the one in greater quantity is called as solvent.

So here the solute is :

a) 30.0 mL of methyl alcohol

b) 1.50 g of NaCl
