Edexcel IAL Chemistry AS 1.2 Moles and Avogadro constant
Edexcel IAL Chemistry AS 1.2 Moles and Avogadro constant
Convert the given quantity to mass or volume if needed, divide by molar mass to obtain moles and multiply by the Avogadro constant and particle ratio.
How this is tested
- Calculate atoms, molecules or ions using moles and the Avogadro constant.
- Convert density and volume to mass before calculating amount and particle number.
- Calculate mole percentages or particles per object from mixed quantitative data.
