Question
8) In order to prepare an experiment, you
weighted a reactant in a balance and it
reads 1.0236. Which is/are the digit(s) with
uncertainty/uncertainties?
а) 36
b) 6
c) 236
d) 0236
9) Choose the correct statement regarding
to the certainty of data measured in a
laboratory
a) We get a better certainty of data by
analyzing a sample with the highest
tolerated amounts of significant figures
b) The amounts of significant figures is
irrelevant, therefore the certainty is
independent of that
c) The certainty of the results depends only
on the half of significant figures of a given
result/datum
d) In order to get a satisfactory level of
certainty in chemical experiments is only
necessary 1 significant figure
10) Which is the correct scientific notation?
а) 1,600.0
b) 1,600
c) 1.6 x 103
d) 1,6 x 103
