What is the specific gravity of mercury, the liquid used in thermometers, if it has a density of 13.6 g/mL?

13.64.

Explanation:

Hello,

In this case, since the the specific gravity is computed as the ratio of the density of the given substance by the density of water that is approximately 0.997 g/mL as shown below:

In such a way, for this case, we find:

Which is dimensionless due the g/mL simplification.

Best regards.

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

imma come back to you hold on
