A technician checks the density of a liquid used in a storage tank. The liquid is added to the same measuring cylinder between the two measurements.
| Volume of liquid in cm3\text{cm}^{3}cm3 | Mass of measuring cylinder and liquid in g\text{g}g |
|---|---|
| 20.0 | 91.6 |
| 100.0 | 183.6 |
Calculate the density of the liquid in g/cm3\text{g/cm}^{3}g/cm3.
Use both measurements from the table.
A tank contains 0.080 m3 of this liquid. Calculate the mass of liquid in the tank in kilograms.
A sealed plastic marker has a mass of 54.0 g and a volume of 50.0 cm3. It is released below the surface of the liquid. The technician claims that it will remain submerged.
Evaluate this claim.
