ChemistryCalculations, moles and yieldGCSEOCR Created by: Caitlin WardCreated on: 06-10-13 20:52 Diluting The opposite of concentrating 1 of 6 Equation to work out how much water you need to add Volume of water to add = (starting concentration / target concentration -1) X Starting Volume 2 of 6 Example 1 of using dilution Concentrated orange cordial needs to be diluted to make sure the taste is too strong 3 of 6 Example 2 of using dilution Medicines may need to be diluted to prevent overdose 4 of 6 Example 3 of using dilution Baby milk must be of the correct concentration so it does not harm the baby 5 of 6 Question: A scientist wanted to dilute 10cm cubed of a 0.5 mol/dm cubed solution to 0.1 mol/dm cubed. How much water should be added? (0.5 / 0.1 -1) X 10 = 40cm cubed 6 of 6
