Equations

Units are found in brackets!

number of moles =

mass (g) / molar mass

(In cm³) number of moles of gas =

volume of gas (cm³) / molar volume of gas (24000cm³)

(In dm³) number of moles of gas =

volume of gas (dm³) / molar volume of gas (24dm³)

(When you have molar mass and concentration in mol/dm³), concentration (g/dm³) =

concentration (mol/dm³) x M_r

(When you have mass of the solute and volume of solution), concentration (g/dm³) =

mass of solute / volume of solution (dm³)

concentration (mol/dm³) =

moles of solute / volume of solution (dm³)

parts per million, ppm =

(mass of solute / mass of solution) x 10⁶

percentage yield =

(actual yield / theoretical yield) x 100

What is this equation? n = m/M_r

number of moles = mass / molar mass

What is this equation? C = n/V

concentration = moles of solute / mass of solution
