specific gravity:

Question

Suppose the hydrometer has a cylindrical stem of cross-sectional area 0.400 cm2. The total volume of the bulb and stem is 8.8 cm3 and the mass of the hydrometer
is 4.8 gm.

(c) What is the lowest specific gravity that can be measured with this hydrometer?

I'm not sure how to start this question, can anyone tell me what to do?

Thanks.

Answer 1

well if the density of the fluid is less than the density of the hydrometer, the hydrometer sinks.

spgr fluid>4.8/8.8

Answer 2

Thanks!
