How to calculate the mass and number of moles in tonne?

consider the reaction: Cl2 + Br- ------> 2CL- + Br2

In trhe production of 1 tonne of bromine, what mass of chlorine is required?


Basically for any reaction, if it gives you the mass in tonnes, what principle do you use?

First balance your equation.

Assume 1 tonne = 1000 kg.

Then use n = m x Mr to work out moles of Bromine.

Then using stoichiometric ratios, work out moles of Chlorine required.

well a tonne is 1000kg which is 1,000,000 g. So you just calculate it how you normally would when you are given a mass.
