Aflask weights 45.4 g when it is empty and 121.8 g when filled with water. when the same flask is filled with another liquid, the mass is 91.39 g. what is the density of the second liquid?

The answer to your question is: 1.19 gr/ml

Explanation:

empty flask weighs = 45.4 g

filled with water = 121.8 g

filled with a different substance = 91.39 g

density of the second liquid =

First we must calculate the mass of water in the flask by subtracting the flask filled with water and the flask empty.

mass =  flask filled with water - the flask empty.

mass = 121.8 - 45.4 gr

mass = 76.4 gr

The density of water is always 1 gr/ml

and density is mass/volume

from here we calculate the volume = mass/density

                                             volume = 76.4/1 = 76.4 ml

Now we calculate the density of the other liquid

           density = 91.39/76.4 = 1.19 g/ml

what are the options.
