How many grams of ALCL₃ must decompose in order to produce 3.10 dm^3 of Cl₂ at 50.0degrees C and 98.4 kPa?

You definitely need to start by writing a balanced equation:

Code: Select all

2AlCl3 = 2Al + 3Cl2

Then the solution need to go as follows:
1) Compute the number of moles of Cl₂
2) Compute the number of moles of AlCl₃
3) Compute mass of AlCl₃

Hope this will help
