Need two of the methods for polycyclic aromatic hydrocarbons degradation. I know one of the method is Photocatalysis but i dont know how it works please help me give me some of the ideas please
Liquid nitrogen has a density of 0.807 g/mL at -195.8 °C. If 1.00 L of N2(l) is allowed to warm to 25°C at a pressure of 1.0 atm, what volume will the gas occupy.

A solution is prepared by dissolving 17.75 g Sulfuric acid (H2S04;MW = 98.0g/mol) in 93.2 g of water. If the density of the solution is 1.1094g/mL, what is the molarity of the sulfuric acid?
