Question

The environmental parameters, temperature, relative humidity and pressure are recorded during a precise mass measurement in a laboratory. 21°C, 56 % RH and 101.8\times10^3 Pa, respectively. Calculate the \"real\" air density in the laboratory. [3 marks] The electronic balance was calibrated using F1 standard mass (made of stainless steel, density = 8000 kg/m³). When we used this electronic balance to weigh a specimen, foam sample, we got the reading of balance (mass of sample) of 185.0000 grams. Given that the density of the specimen is 2600 kg/m³. Calculate the corrected mass value (in gram) of the specimen with the conditions measured in part (d) (i). [2 marks]
