Displacement Method, What is the density of citric acid
The displacement method is a straightforward technique for determining the density of a liquid. A known volume of a liquid is carefully measured using calibrated glassware. The sample is then added to the measuring container, and the new volume is measured. The difference between the initial and final volumes represents the volume of the sample. The mass of the sample is determined using a calibrated balance.
The density is calculated by dividing the mass by the volume of the sample. This method requires precise measurements of volume and mass. Errors can arise from inaccuracies in measuring glassware or variations in the temperature of the sample.
