Aflask containing 9.51 ml of a liquid weighs 156.1 g with the liquid in the flask and 148.4 g when empty. calculate the density of the liquid in g/ml to the correct number of significant digits

Answer : The density of liquid in g/ml is, 0.81 g/ml

Explanation : Given,

Volume of liquid = 9.51 ml

First we have to calculate the mass of liquid.

Mass of liquid = Mass of flask and liquid - Mass of empty flask

Mass of liquid = 156.1 - 148.4

Mass of liquid = 7.7 grams

Now we have to calculate the density of liquid.

Formula used :

Now put all the given values in this formula, we get the density of liquid.

The rule apply for the multiplication and division is the least number of significant figures in any number of the problem determines the number of significant figures in the answer.

Hence, the density of liquid in g/ml is, 0.81 g/ml
