They have a brief squabble then Charlie goes to the waiting room to clean the floor with a carpet sweeper. He bumps into a patient and a further squabble starts. Then back to the rear room for more
Gas collecting tube the fluid to be investigated. Measure the overall mass formula_2 to calculate the mass of the fluid inside the tube formula_27 yielding the desired mass density formula_12. If the gas is a pure gaseous chemical substance (and not a mixture), with the mass density formula_12, then using the ideal gas law permits to calculate the molar mass formula_30 of the gaseous chemical substance: formula_31 (formula_32 represents the universal gas constant, formula_33 the absolute temperature at which the measurements took place) Gas collecting tube The characterization gas collecting tube describes an oblong gas-tight container with one valve at either end.
