Answer:
The answer to your question is: 1.19 gr/ml
Step-by-step 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
