Fractional CompositionDerive the fractional compositions for monoprotic and diprotic systems showing the steps as clear as possible including a brief description of a fraction compostion plot. And if possible throw in examples, so I can understand it better.
Gaseous hydrogen has a density of 0.0899g/L at 0 degrees Celsius. How many liters would you need if you wanted 1.0078 g of hydrogen?
Calculate the molecular rms speeds of He atoms at 10, 100, 1000 K in units of meters per second and miles per hour.
