Calcium hypochlorite ( ca(ocl)2ca(ocl)2 , mw = 142.983 g/mol) is often used as the source of the hypochlorite ion ( ocl−ocl− , mw = 51.452 g/mol) in solutions used for water treatment. a student must prepare 50.0 ml of a 20.020.0 ppm ocl−ocl− solution from solid ca(ocl)2ca(ocl)2 , which has a purity of 92.092.0 %. calculate the mass of the impure reagent required to prepare the solution. assume the density of the solution is 1.00 g/ml.

It's not the same dearthe first one is in grams per mole while the other is not

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.
