Table 2.3
Problem
36. A chemist recorded the data in Table 2.3
below in an experiment to determine the composition
of a
compound of
position of three samples
masi
different sources. Determine the ratio of m
copper (Cu) and sulfur (S) obtained from t
of copper to mass of sulfur for each sample,
How do these ratios compare? What law of
chemistry does this experiment illustrate?
Does the result mean that atoms of c
sulfur occur in this compound in the
numerical ratio? Explain your answer.
