Which substance contains the greatest mass of bromine?
a) 60.0g NaBrO3
b) 30.0g MgBr2
c) 5.0g HBrO4
d) 0.10 mol KBr
e) 0.10 mol HBr
To solve this problem you need to calculate the masses of bromine in each compound in order to determine which has the greatest mass
I will go through the steps in detail for NaBrO3, and you should be able to apply this to all 4 of the other compound.
Steps to determining the mass of bromine in a chemical:
1. Determine the number of mols of the compound:
This can be accomplished using the formula mols = mass/molar mass. For NaBrO(3) we have already been given the mass so we only need to calculate the molar mass from the formula. This is done by adding up the molar masses of each compound involved paying close attention to the ...
The mass of bromine in each compound is calculated by determining the number of moles of each compound, the number of moles of bromine in each compound and then the mass of bromine of that number of moles. This answer goes through the steps in detail for NaBrO3, and then applies them to the other four compounds. 500 words.
