Chemistry Topic 13 and 14 0.0 / 5 ? ChemistryallIGCSEEdexcel Created by: Sophie RussellCreated on: 20-02-14 20:46 T13- What is Avogadro's Law? One mole of any gas occupies 24dm^3 at room temperature and pressure (1 atmosphere.) 1 of 10 T13- What is the molar volume? The space that one mole of gas takes up. 2 of 10 T13- What is the conversion between cm^3 and dm^3? 1000 cm^3 = 1 dm^3 3 of 10 T13- What is the triangle to use regarding volumes? Volume on top with number of moles and 24 below. 4 of 10 T13- How do you find volumes in reactions? You calculate masses in reactions, and then convert to volume. 5 of 10 T14- Define 'concentration.' Moles per unit volume. (Amount of particles per volume.) 6 of 10 T14- What is the unit for concentration? mol/L= mol/dm^3 = mol dm^-3 7 of 10 T14- What is the triangle used regarding concentration? Number of moles at the top, concentration below to the left and Volume below to the right. 8 of 10 T14- How would you find g/ dm^3? Simply divide the mass by the volume (maybe RTP where 1 mole of gas = 24 dm^3) 9 of 10 T14- How would you convert from mol/ dm^3 to g/dm^3? Use the triangle where mass is on top, and number of moles and relative formula mass are below. 10 of 10
