Question

How do I get the actual yield of NaCl?

Answer 1

79.77 g (150-mL beaker)

81.96 g (150 mL + NaHCO3)

80.56 g (150 mL + NaCl after incubated)

Answer 2

I feel like my incubated mass is too small.. o.o

Answer 3

\[Amount\ NaHCO_3=(81.96g-79.77g)=2.19g*\frac{1mol}{84.007g}=0.0261mol\ NaHCO_3\]\[Amount\ NaCl = (80.56g-79.77g)=0.790g*\frac{1mol}{58.443g}=0.0135mol\ NaCl\]Do you know how to find the actual yield from that information?

Answer 4

do I subtract 80.56 g from 79.77?

Answer 5

wait, what?

Answer 6

I'm trying to find the percent yield of sodium chloride

Answer 7

Percent yield is defined as the percentage of species actually produced when compared to the amount of species that was theoretically supposed to be produced.

First identify how much NaCl you were SUPPOSED to have theoretically produced.
