2. Perform the following concentration conversion calculations: (a) (4) A swimming pool requires a chlorine (Cl2) residual of 2.0ppm (on a mass basis) to discourage the growth of bacteria. If the pool contains 2,500,000L, what mass of chlorine must be added to obtain the desired chlorine level? (b) (6) The air quality index in Beijing last year recorded average ozone (O3) levels of 110ppb (on a mol basis). Does this exceed Canada's acceptable 24 hour National Ambient Air Quality Objective (NAAQO) of 50g/m3 ? Assume the average molar mass of air is 29.0g/mol and its density is 1.225kg/m3
