Worked Solution & Example Answer:The concentration of a solution can be calculated using the equation concentration of solution = mass of solid / volume of solution A student dissolved 9.25g of ammonium chloride in water and made up the solution to a volume of 200 cm³ - Edexcel - GCSE Chemistry - Question 2 - 2021 - Paper 1
Step 1
Use the equation to calculate the concentration of this solution in g dm⁻³.
Answer
To find the concentration of the solution, we will use the formula:
ext{concentration of solution} = rac{ ext{mass of solid}}{ ext{volume of solution}}-
Convert the volume from cm³ to dm³:
- Since 1 dm³ is equal to 1000 cm³,
- We convert 200 cm³ to dm³:
-
Substitute the values into the equation:
- Mass of solid = 9.25 g
- Volume of solution = 0.2 dm³
-
Final answer:
- The concentration of the solution is 46.25 g dm⁻³.
