Aflask contains 0.330 mol of liquid bromine, br2. determine the number of bromine molecules present in the flask. express your answer numerically in molecules.

One mole of br2 contains 6.02 * 10^23 Avogadro particles 
It follows that 0.330 moles contains X.  
Hence it follows that X = 0.330 * 6.02 * 10^23 
X = 1.9866 * 10^23 
X = 198660000000000000000000

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid
