| Question | Answer |
| Define Concentration | The concentration of a solution is the amount of solute, in moles, dissolved in each 1dm3 (100cm3) of solution |
| 10cm3 = _____ml3 | 10ml3 |
| 1dm3 = ____cm3 = ____ l | 1dm3 = 1000cm3 = 1l |
| What is the equation linking, amount, concentration and volume? | Amount (mol) = (Volume*concentration) / 1000 (Only divide by 1000 if volume in cm3!) |
| What is a standard solution? | A standard solution is one of known concentration |
| What is the Ideal Gas Equation | pV = nRT |
| Give the name and unit of the constituents of the ideal gas equation | p = pressure in Pa V = volume in m3 n = amount in moles R = Gas constant of 8.13 T = Temperature in Kelvin |
| How do you convert kPa to Pa? | x1000 |
| How do you convert: a) cm3 to m3 b) dm3 to m3 | a) *10^-6 b) * 10^-3 |
| Convert 10 degrees to kelvin | = 10 + 273 = 283 kelvin |
| What is the molar gas volume? | The molar gas volume is the volume per mole of gas molecules at room temperature and pressure (RTP) |
| Converting between amount and gas volume (cm3) | amount (mol) = Volume (cm3) / 24000 |
| Converting between amount and gas volume (dm3) | amount (mol) = Volume (dm3) / 24 |
