Molarity Calculations Examples
Molarity Calculation Problem Example : If one mole of potassium chloride (74.55g/mole) is dissolved in 1dm3 of solution, the result is a one molar solution of potassium chloride.
Molarity Calculation Problem Example 2: If half a mole of potassium chloride is dissolved in 1dm3 of solution, the result is a 0.5 molar solution of potassium chloride.
Molarity Calculation Problem Example 3: If 0.217 mole of potassium chloride is dissolved in 5dm3 of solution, the result is a (0.217mole)/5dm3 = 0.0437 molar solution of potassium chloride.
Molarity Calculation Problem Example 4: If 105.45 grams of potassium chloride (74.55g/mole) is dissolved in 2dm3 of solution, the result is (105.45g/(74.55g/mole))/2dm3 = 0.707 molar solution of potassium chloride.
NOTE: Water is added to the volumetric flask up to the one liter line.
CHEMIX solution - Molarity Calculations - Example 4
In Molecular Calculator insert 105.45gKCl in the formula text field and Calculate. Then divide the resulting mole amount in Calculated values by two (2dm3).
