what is stoichiometry ?
Stoichiometry is the ratio of moles of reactants and products in chemical reactions.
what is the concentration of a solution ?
the amount of solute dissolved in a solvent to make 1 dm3 of solution
what is the equation that links conc, mol and vol ?
conc (mold dm-3) = number of moles (mol)/ volume of solution (dm3)
what is avogadros hypothesis ?
Avogadro suggested that ‘equal volumes of gases contain the same number of molecules’ (also called Avogadro’s hypothesis)
what is the volume of one mole of gas at rtp ?
24.0 dm3 mol-1
how can you find the volume of a given mass of moles of gas using the molar gas volume ?
volume of gas (dm3) = amount of gas (mol) x 24 dm3 mol-1
