LEARNING MODULE 3 2026 COMPLETE EXAM
PRACTICE WITH MARK SCHEME
◉ volume
(unit, unit symbol, definition). Answer: cubic meter, m^3
also allowed:
- cubic decimeter, dm^3
- cubic centimeter, cm^3
measure of the amount of space occupied by an object
◉ cubic decimeter also known as. Answer: liter, L
◉ cubic centimeter also know as. Answer: mL
healthcare professionals abbreviate as: cc
◉ density
(unit, unit symbol, definition). Answer: kg per cubic meter, kg/m^3
, For solids and liquids:
- grams per cubic centimeter, g/cm^3
- grams for milliliter, g/mL
for gases: grams per liter, g/L
The ratio of the mass of a sample of the substance to its volume
◉ Calculation of density. Answer: Density=mass/volume
◉ calculation of mass. Answer: mass=density x volume
◉ Calculation of Volume. Answer: volume=mass/Density
◉ exact number. Answer: derived from counting and numbers of
defined quantities, no uncertainty
◉ uncertain measurement. Answer: quantities derived from
measurements other than counting, have inherent uncertainty due
to the limitations of the measurement process
◉ uncertainty. Answer: estimate of amount by which measurement
differs from true value
