Pure substances are defined as substances that are made of only one type of atom or only one type of molecule (a group of atoms bonded together). The measure of whether a substance is pure is known as purity. For example, pure iron would only contain iron atoms, and, as in the sugar cube mentioned above,...

A pure substance is a substance that cannot be separated by physical means. eg. filtration, evaporation, distillation or chromatography. Examples of pure substances include water, gold, glucose, carbon dioxide, oxygen and hydrogen. A pure substance is made up of one type of particle. The particle that makes up water is H2O. The particle that makes up carbon dioxide is CO2. Each pure substance has its own set of unique set chemical and physical properties which helps identifies it. Water has a melting point of 0°C and a boling point of 100°C. It is also colorless and odorless. Gold however, is yellow in color, solid at room temperature and pressure and is is good conductor of electricity. read less

in very simple terms pure substances are those which are formed by only one type of atom or one type of molecule(group of atoms). like pure iron would contain only iron molecule and nothing else.

Calculate the mass of 0.5 mole of N2 gas (mass from mole of molecule).
Molar mass of N2 is 28(since atomic weight of nitrogen is 14and forN2=14*2). So mass of 1 mole of N2 is 28g.Therefore mass of 0.5 mole is 28/2 =14g
