Chemistry question help please!!!!

U'm really confused, please help

Make a balanced symbol equation, using the data from this experiment.
Reactants
CaCl2= 666g
Products
Ca = 240g
Cl2= 426g

Have you attempted the question? How do you think you might start it?

I've worked it out now.
mols of Ca= mass/Mr =240g/40=6 mol
mols of Cl2=426g/(35.5+35.5)= 6 mol
Mols of CaCl2= 666/(40+35.5+35.5)= 6mols
This means the Equation would be 6CaCl2 --> 6Ca + 6Cl2
I hope this is right.

This can be simplified into CaCl2 --> Ca + Cl2

This question really doesnt make sense, the balanced equation would just be CaCl2 ---> Ca + Cl2, I dont get why theyre asking u this or why theyve given u masses. It would make more sense if it wanted the actual stoicheometric mole values, where u would do mole calculations, but for balanced equation u dont need to do that
