General Chemistry 1 Lab- Experiment 1
Questions And Correct Answers
Answer the mass contained in the material per unit volume
Derived quantity - Correct Answer taking its unit from the mathematical relationship
Density formula - Correct Answer Density= mass (g) ➗ volume (cm^3)
How to find mass? - Correct Answer weighing the material on a balance
"weight" - Correct Answer the gravitational attraction for the matter
"Mass"-"Weight" - Correct Answer "mass" of the material is equivalent to the "weight"
of the object on Earth at sea level
Volume - Correct Answer use an appropriate calibrated volumetric device
PYCNOMETER
Volumes of solids - Correct Answer measured directly with distances such as length,
depth, width and/or diameter for objects
Solids of irregular shapes - Correct Answer most readily found by measuring the
displacement of water within the volumetric device
Mass of unknown liquid - Correct Answer mass of the unknown liquid= (mass of flask
and unknown liquid) ➖ (mass of flasks)
Volume of flask - Correct Answer volume of flask= volume of H20 in flask= mass of
H20 ➗ density of H20
How does density change with temperature? - Correct Answer volume changes with
temperature
How should the density of solid differ from the density of a liquid? - Correct Answer by
the dense state
