Question

12.8 ml of a solution is run into an empty flask, from a buret. The mass of the empty flask is 144.0 g. The mass of the flask plus solution is 155.5 g. The density of the solution is _____ g/ml

Answer 1

Answer:

0.8984g/ml

Explanation:

Mathematically, the density of a liquid can be obtained by dividing the mass by the volume.

Hence, to get the answer for the density in the above question, we need to divide the mass by the volume.

Now, let’s get what the mass is. Mass of solution = mass of flask and solution - mass of empty flask = 155.5 - 144.0 = 11.5g

We then proceed to get the density.

The volume is 12.8ml.

The density is thus 11.5/12.8 = 0.8984g/ml
