Chloroform is a reagent used often in Nuclear Magnetic Resonance Spectrometry. If the apparent mass weighed in air is 7.5270 g, what would be the absolute percentage error if the mass is not corrected for buoyance? Chloroform’s density = 1.49 g/mL and the air pressure is 710 mmHg, air temperature is 27°C and relative humidity is 75%.
