Establish the rules in significant figures and calculate the mass of liquid using weigh by difference then determine the density per g/mL
In order to determine the density of the liquid, we have to calculate for the mass of the liquid:
Remember the rules for the significant figures in calculations.
A flask containing 7.50 mL of a liquid weighs 168.1 g with the liquid in the flask and 160.1 g when empty.
Calculate the density of the liquid in g/mL to the correct number of significant digits.
