How do calculate the Relative Formula Mass
adding the atomic masses
how do calculate the percentage Mass
mass of X / RFM (x 100)= %
what is the equation for moles
moles= mass (g) /RFM
What is the equation for mass
mass = Mole x RFM
How do you calculate the % Yield
% Yeild = Actual / Theoretical (x 100)
when you lay out the table for the Empirical formulae what is the order
Mass RFM mole ratio table method divide by the smallest
to calculate the value of x which method should you use
the table method same as Empirical formular
what is the first step to working out the molecular formulae
Working out the mass of the atom by adding together all the elements in the atom then divide by the RFM given then times each element by the answer you just worked out above
what number do you use of the element when working out the RFM
Top number- atomic mass
