| Question | Answer |
|---|---|
| triangle ------ mass= | moles x mr |
| triangle ------moles= | mass/mr |
| triangle ------ mr= | mass/moles |
| cm moles= | c x v /1000 |
| cm v= | nx1000 /c |
| cm c= | n x10000/ v |
| gases at rtp. moles= | vx24000 or v x 24 (DM) |
| gases at rtp volume= | n/24000 or n/24 |
| temp . to make degrees into kelvin you.... | add 273 |
| pressure. killer pascal into pascals | you divide by 1000/ 10-3 |
| volume is measured in m3 so | dm -m divide by 10-3 cm-m divide by 10-6 |
| R = gas constant = | 8.314 |
| no of particles | n x 6.02 x 10-23 |
