Using concentrations of solutions in mol/dm? Flashcards
In what unit can the concentration of a solution be measured?
In mol/dm?.
How can the amount in moles or the mass in grams of solute be calculated in a given volume of solution?
From its concentration in mol/dm’.
How can you calculate the concentration of one solution if the volumes of two reacting solutions are known?
If the concentration of one solution is known, you can calculate the concentration of the other solution.
What should students be able to explain regarding solution concentration in mol/dm’?
How it is related to the mass of the solute and the volume of the solution.
What skills are necessary for these calculations?
Recognizing and using expressions in decimal form, using ratios, fractions, and percentages, changing the subject of an equation, and substituting numerical values into algebraic equations with appropriate units for physical quantities.
