- Moles
- Solids
- n= m / Mr
- Mr is the large number on the periodic table
- n= m / Mr
- Liquids
- n = c x vol
- divide VOLUME by 1000 if it is given in cm cubed
- n = c x vol
- Gases
- n = vol / 24
- 24 000 if the volume is given in cm cubed
- n = vol / 24
- Steps to calculating
- find the moles of WHAT YOU KNOW
- figure out the RATIO e.g if it's 2:1, divide the mole of the substance by 2 to find the mole of the other substance
- using the moles find the UNKNOWN e.g volume of gas, concentration of a solution or mass of a solid
- figure out the RATIO e.g if it's 2:1, divide the mole of the substance by 2 to find the mole of the other substance
- find the moles of WHAT YOU KNOW
- Solids
