An empty with an unknown volume is weighed and found to have a mass of 81.2 grams. The container is then filled with a liquid with a density of 1.045 g/cm3 and re-weighed. The mass of the container and the liquid is 161.4 grams. Determine the volume of the container to the appropriate number of significant figures.
Solutions
Expert Solution
Generally we can find the volume of container by filling it with liquid and then measuring the volume of liquid. In the given question also we provided with mass of liquid and density of liquid to measure the volume of liquid, which is same as volume of container.

A student obtained an unknown metal sample that weighed 65.3 g and
at a temperature of 99.8oC,
he placed it in a calorimeter containing 43.7 g of water at
25.7oC.
At equilibrium the temperature of the water and metal was
34.5oC.
Knowing the specific heat of the water to
be 4.18 J/goC,
what is the specific heat of the metal?

You weighed a solid sample of an unknown mixture of carbonate
and bicarbonate to be 5.3431 grams. You properly dissolved the
entire unknown solid sample in 250.0 mL of boiled and cooled
distilled water. You then performed two trials of 25.00 mL aliquot
of the unknown solution titrated with 0.1389 M standardized HCl
using a pH probe yielding: trial 1:{volume HCl (mL), pH} = {{1.090,
12.15}, {9.190, 12.13}, {17.290, 12.33}, {25.590, 12.35}, {33.800,

The mass of an empty flask is determined on a balance. It is
then filled with N2 and its mass measured. The same flask is then
evacuated of N2 and refilled with an unknown gas at the same
temperature and pressure and its mass determined.
Mass of empty flask = 88.15g
Mass of flask and unknown gas = 91.30g
Mass of flask and N2 = 89.67ga.
