values that have trailing zeros only to the left of the decimal point are ambiguous and should be expressed in scientific notation. We must take note that the chemistry textbook (Silberberg 6e) states that placing a decimal point to the right of some trailing zeros (example: 300.) will make the zeros significant. However in General Chemistry‚ we do not follow this rule. If we want to write a whole number with trailing zeros we must use scientific notation to show which zeros are significant. When
