Measurement and Unit Conversions
Significant Figures and Scientific Notation
Density and Dimensional Analysis
Matter: Elements, Compounds, and Mixtures
Atomic Theory and Structure
Periodic Table and Periodic Trends
Naming Compounds and Writing Formulas
States of Matter and Kinetic Molecular Theory
Chemical and Physical Changes
Energy and Thermodynamics
Chemical Bonding
Nuclear Chemistry and Isotopes
This comprehensive examination is designed to evaluate
foundational knowledge and problem-solving skills in general
chemistry. The assessment covers key topics including unit
conversions, significant figures, scientific notation, density
calculations, classification of matter, atomic theory, periodic
trends, chemical nomenclature, states of matter, and energy
concepts. Through a series of multiple-choice and calculation-
based questions, students will demonstrate their ability to apply
fundamental chemistry principles to solve problems and interpret
chemical phenomena. The exam emphasizes critical thinking,
,quantitative reasoning, and the application of chemical concepts
to real-world scenarios. Successful completion of this exam
indicates readiness for advanced study in chemistry and related
sciences.
SECTION ONE: QUESTIONS 1 – 100
1. Convert 3.59 kg into grams. Do not include units in your
answer.
A. 0.00359
B. 35.9
C. 359
D. 3590
D. 3590
RATIONALE: There are 1000 grams in 1 kilogram. Multiply
3.59 kg × 1000 g/kg = 3590 g.
2. Convert from 2000.4 mm to kilometers. Do not include
units in your answer.
A. 0.0020004
B. 0.20004
C. 2000400
D. 2000040
A. 0.0020004
RATIONALE: There are 1,000,000 mm in 1 km (1000 mm/m
× 1000 m/km). Divide 2000.4 mm by 1,000,000 = 0.0020004 km.
3. Convert 62 picometers to millimeters. Do not use units or
scientific notation in your answer.
,A. 0.000000062
B. 0.0000062
C. 0.0000000062
D. 6.2e-8
D. 6.2e-8
RATIONALE: 1 picometer = 10⁻¹² m and 1 millimeter = 10⁻³
m. 62 pm × (10⁻¹² m/1 pm) × (1 mm/10⁻³ m) = 62 × 10⁻⁹ mm =
6.2 × 10⁻⁸ mm.
4. Convert 5.45 micrograms to femtograms. Do not include
units in your answer and do not use scientific notation.
A. 5450000000.0
B. 5450.0
C. 0.000000545
D. 54500000000.0
A. 5450000000.0
RATIONALE: 1 microgram = 10⁻⁶ g and 1 femtogram = 10⁻¹⁵
g. 5.45 μg × (10⁻⁶ g/1 μg) × (1 fg/10⁻¹⁵ g) = 5.45 × 10⁹ fg =
5,450,000,000.0 fg.
5. Convert 35 centigrams to grams. Do not include units in
your answer.
A. 0.035
B. 0.35
C. 3.5
D. 350
B. 0.35
, RATIONALE: There are 100 centigrams in 1 gram. 35 cg × (1
g/100 cg) = 0.35 g.
6. Convert 0.067 microliters to liters. Do not include units
in your answer.
A. 6.7 × 10⁻⁸
B. 6.7 × 10⁻⁷
C. 6.7 × 10⁻⁶
D. 0.000067
A. 6.7 × 10⁻⁸
RATIONALE: 1 microliter = 10⁻⁶ L. 0.067 μL × (10⁻⁶ L/1 μL) =
6.7 × 10⁻⁸ L.
7. How many significant figures are in the following
number? 100
A. 1
B. 2
C. 3
D. Ambiguous
A. 1
RATIONALE: Trailing zeros in a whole number without a
decimal point are not significant. Only the digit "1" is
significant.
8. How many significant figures are in the following
number? 0.00090
A. 1
B. 2
