Interpretation:
The molecular mass of
Concept Introduction:
Uncertainty:
Uncertainty means state of not certain in predicting a value. In a measured value, the last digit will have associated uncertainty. Uncertainty has two values, absolute uncertainty and relative uncertainty.
Absolute uncertainty:
Expressed the marginal value associated with a measurement
Relative uncertainty:
Compares the size of absolute uncertainty with the size of its associated measurement
For a set measurements having uncertainty values as
Percent relative uncertainty:
(b)
Interpretation:
The molarity of
