GCSE Chemistry - How to Calculate Concentration in grams per decimetre cubed #30

The video tutorial explains how to calculate the concentration of a solution in grams per decimeter cubed. It introduces the concept of decimeter cubed as a volume measurement equivalent to 1000 centimeters cubed or one liter. The tutorial uses a formula triangle to simplify the calculation of concentration, mass, and volume. It provides examples with sodium hydroxide and copper sulphate to demonstrate concentration calculations and highlights the importance of unit conversion. Additionally, it shows how to calculate mass from given concentration and volume using hydrochloric acid as an example.

What is the importance of checking the units of the figures given in a concentration problem?

How would you calculate the mass of hydrogen chloride in a solution with a concentration of 20 grams per decimeter cubed and a volume of 400 centimeters cubed?
