Hi there,
Answer
A molal solution is number of mols divided by 1000g solvent.
So 1.135m solution is 119g x1.135 g of KBr in 1000g water = 135.07g
The total mass would be 1135.07g and the volume would be dependant on the density which is not given in the question.
You cannot therefore calculate the mass in 500ml without knowing the density..
