CHM 113 TEST BANK 2026 EXAM REVIEW WITH
SOLVED QUESTIONS GRADED A+
◉ Specific Gravity. Answer: The ratio of the density of a substance to
the density of water
◉ Intensive property. Answer: Properties independent of mass.
Examples: density, specific heat, equivalent weight
◉ Extensive property. Answer: Properties dependent of mass. Example:
volume and mass
◉ Volume of a cylinder. Answer: V = pi(r)^2h
◉ Mass of water displaced by a rock with 143g in air and 82 g in water.
Answer: Mass of water displaced = Mass of rock in air - mass of rock in
water
◉ Volume of water displaced by a rock. Answer: V = mass of water
displaced divided by density of water
,◉ Density of rock with 143g in air, 82 g in water. Answer: = mass of
rock in air divided by the volume it displaces in water
◉ If a piece of PVC is suspended in solution than the density of the PVC
is. Answer: equal to the density of the solution
◉ Which has a greater density: water or ice?. Answer: Water (Ice floats
on water)
◉ What are the units of density?. Answer: g/mL and g/cm^3
◉ Why is density important?. Answer: It identifies a substance
◉ What is the conversion factor of cm^3 and mL. Answer: 1 cm^3 = 1
mL
◉ What is the normal order of density for the states of matter?. Answer:
Gas is the least dense, liquid is more dense and solid is the most dense.
◉ What property of adipic acid is used in the separation during the
adipic acid lab?. Answer: solubility
◉ What is the formula for Adipic Acid?. Answer: H2C6H8O4
, ◉ What is the unit of specific heat?. Answer: there is no unit
◉ What does density tell us?. Answer: Density relates information on
how the atoms or molecules that make it up are arranged in space.
Substance with larger density is more tightly packed than the substance
with smaller one.
◉ What is the structure of adipic acid?. Answer:
HOOCCH2CH2CH2CH2COOH
◉ What is adipic acid used for?. Answer: Production of nylon; additive
to drinks
◉ Solubility of Adipic Acid. Answer: Adipic acid's solubility is
temperature dependent. It is more soluble in hot water and slightly
soluble in cold water. This property is the principle of recrystallization
of adipic acid.
◉ What impurities make the crude adipic acid brown?. Answer:
Oxidized compounds and fine carbon particles.
◉ What substance absorbs the impurities?. Answer: Charcoal. One
scoop is added to the beaker.
