You are given 7.80g of Bromine gas in a container. Under identical conditions, you have 12.8g of an unknown gas. What is the molar mass of the unknown gas?
- so, considering the molar mass of Bromine that I used was 159.808g/Mol, I did:
7.80g Br / 159.808g/mol = 12.8g unknown gas / molar mass of unknown gas
Molar mass of unknown gas = 262g/Mol
Is this correct?
