What is the mass (g) of 0.95 mol of the element bromine (Br)?

Answer 1

#"1 mole of bromine atoms"# has a mass of #79.9*g#.

Of course, we normally encounter bromine as the bromine molecule, #Br_2#.

As to your question, the mass is simply the product of moles and atomic mass: #0.95*cancel(mol)xx159.8*g*cancel(mol^-1)# #~=# #150*g#

Bromine is one of the few elements that is a liquid under normal conditions. There are few things in a laboratory that are as dangerous and corrosive as neat bromine. If you have to use it, you should treat it with some respect.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
