What is the molarity of a solution with 23 moles of solute, and 100 ml of a solvent?
Marina CMI [18]
Molarity is calculated by using following formula,

                            Molarity  =  Moles / Volume

Data Given:
                  Moles  =  23 moles

                  Volume  =  100 ml ÷ 1000  =  0.1 L

Putting values in eq. 1,

                              Molarity  =  23 mol / 0.1 L

                              Molarity  =  230 mol/dm³

Result:
           When 23 mol of solute is dissolved in a solvent to make a solution of 100 ml, then it will have a Molarity of 230 mol/dm³.

Caclulate the pH of a solution with a hydrogen ion concentration of 1X10-7
LUCKY_DIMON [66]

Answer:

The pH of the solution is 7.00 .

Explanation:

The pH gives us an idea of the acidity or basicity of a solution. More precisely, it indicates the concentration of H30 + ions present in said solution. The pH scale ranges from 0 to 14: from 0 to 7 corresponds to acid solutions, 7 neutral solutions and between 7 and 14 basic solutions. It is calculated as:

pH = -log (H30 +)

pH= -log (1x10^-7)

<em>pH= 7.00</em>
