Question

A bulb is filled with 10^-4 g of N2O5 molecules. How many moles and molecules of N2O5 are in it? N2O5 decomposes as N2O5 -> 2NO2+ 1⁄2 O2. How many molecules would be in the bulb at the end of this reaction? Would the sample still weighs 10^-4 g? Please help ​

Sea water is a mixture of salts and water which cannot be separated except by evaporation. Therefore, sea water is considered homogeneous.

Sea water also contains mud, decayed plant, etc., other than salts and water, so it is heterogeneous also.
