Interactive Drill Problems
The following links point to pages where you can practice certain calculations in
chemistry. They were developed by Professor George Wiger at Caifornia State
University, Dominguez Hills.
Drill on counting significant
figures
Drill on predicting
exponents in calculations (works with Netscape only)
Drill on expressing in
scientific notation
Drill on interconverting wavelength,
frequency, and energy
Drill on relative masses
from chemical formulas
Interconversion of mass
and moles of elements
Interconversion of mass,
moles, and gram formula (molecular) weights
Drill on using bond
energies to calculate energy change in chemical reactions
Relating Molarity, Moles
and Volume
Relating Molarity,
Mass and Volume (a little more complicated)
Interconverting [H^{+}],
[OH^{}], pH and pOH
