Questions

  1. 1Based on the lab data for Isopropyl Alcohol, if the mass of the liquid is 23.637 g and the volume is 29.97 mL, what is the calculated density to the correct number of significant figures?
  2. 2When measuring a cylindrical solid in this lab, which geometric formula should be used to calculate its volume?
  3. 3An irregular object is placed in a graduated cylinder. The initial water level is 20.1 mL and the final water level is 22.9 mL. What is the volume of the object?
  4. 4If a student recorded a volume measurement for an irregular object that was lower than the actual value, how would this specifically affect the calculated density?
  5. 5If a student mistakenly used the mass of only one rubber stopper but recorded the volume of two rubber stoppers, what is the result on the density calculation?
  6. 6Using the density of aluminum (2.70 g/cm³), calculate the volume occupied by 50.0 g of aluminum using dimensional analysis.
