Answer #1

The lengths of the sides (in feet) of a five-sided closed
polygon traverse are as follows:
ABABAB = 204.74, BCBCBC = 263.87, CDCDCD = 462.37, DEDEDE =
312.33, and EAEAEA = 374.78. (Note: Assume units of feet for all
distances.)
The azimuths are as follows:
AB=218∘59′30′′AB=218∘59′30″, BC=147∘45′49′′BC=147∘45′49″,
CD=75∘05′27′′CD=75∘05′27″, DE=336∘56′04′′DE=336∘56′04″,
EA=266∘12′23′′EA=266∘12′23″.

The observed lengths of the sides (in feet) of a five-sided
closed polygon traverse are as follows:
ABABAB = 201.74, BCBCBC =
283.87, CDCDCD = 470.37, DEDEDE
= 330.33, and EAEAEA = 379.78. (Note: Assume
units of feet for all distances.)
The preliminary azimuths obtained after balancing the angles are
as follows:
AB=218∘59′30′′AB=218∘59′30″ ,
BC=147∘45′49′′BC=147∘45′49″ ,
CD=75∘05′27′′CD=75∘05′27″ ,
DE=336∘56′04′′DE=336∘56′04″ ,
EA=266∘12′23′′EA=266∘12′23″ .
a) Computer the departures of the sides.(three sig figs)
b) computer the latitudes of the sides. (three sig...

The coefficients in a balanced chemical equation provide the
mole-to-mole stoichiometry among the reactants and products. The
molar mass (in g/mol) can be used as the conversion factor between
moles and the mass of a substance. Thus, the balanced equation and
molar masses can be used in conjunction with one another to
calculate the masses involved in a reaction.
