| Goal
I. Use SI units to indicate the accuracy and precision of measurements. |
Objectives: To meet the requirements of Goal
I, you must be able to:
- identify
the SI base units
and correct abbreviations for the physical quantities
given in Table 1.2;
- know
the SI prefixes
and their related association factors listed in BOLD
in Table 1.3;
-
convert
from one SI unit to another;
-
distinguish between
accuracy and precision;
-
relate the number
of significant digits used in recording a measured quantity;
-
understand the rules
for:
-
determining the number of significant figures in a reported
measurement
-
for applying significant figures
to the results of the mathematical operations of addition-subtraction and
multiplication-division. [Top]
| Goal II. Apply the rules
of measurement to the properties of mass, volume, density, and temperature. |
Objectives: To meet the requirements of Goal
II, you must be able to:
-
distinguish between:
-
mass, volume and density,
-
extensive and intensive properties,
-
heat and temperature;
-
calculate mass,
volume or density given two of the three quantities;
- convert
temperatures using Celsius, and Kelvin scales.[Top]
| Goal III. Understand the
relationship between the mass of a sample of matter and the number of its
constituent particles. |
Objectives: To meet the requirements of Goal
III, you must be able to:
-
explain and correctly
use the terms: neutron, isotope, mass number, atomic mass unit, hydrate;
-
determine the number
of protons, neutrons and electrons in atoms given the specific isotopic notation and vice versa;
- calculate the
average atomic mass for a naturally occurring element
from isotope percentage and isotope mass;
-
calculate the formula
mass (FM) [also called molar mass (MM)] of a compound, given a molecular
or ionic formula for that compound, and using atomic masses from the periodic
table; Round off and use atomic masses of elements to 2 decimal places for all calculations.
-
define mole,
Avogadro's number and know
the
value to 4 significant figures of Avogadro's number;
-
convert between
mass in grams, moles and numbers of atoms. [Top]
