Answer:

The answer to your question is 471.2 g

Explanation:

Data

moles of Cu(HCO₃)₂ = 2.54

mass of Cu(HCO₃)₂ = ?

Process

1.- Calculate the molar mass of Copper (II) bicarbonate

Cu(HCO₃)₂ = (1 x 63.5) + (2 x 1) + (2 x 12) + (6 x 16)

                  = 63.5 + 2 + 24 + 96

                  = 185.5 g

2.- Use proportions and cross multiplication to find the mass

                     185.5 g of Cu(HCO₃)₂ ------------- 1 mol

                         x                               ------------- 2.54 mol

                                   x = (2.54 x 185.5) / 1

                                   x = 471.2 g

pogonyaev

Answer:

\boxed {\boxed {\sf 60 \%}}

Explanation:

Percent yield is a ratio of the actual yield to the theoretical yield. It is found using this formula:

\% \ yield= \frac {actual \ yield}{theoretical \  yield} *100

The actual yield is 12 liters, because that was actually produced in the lab.

The theoretical yield is 20 liters, because that was the expected yield.

\% \ yield= \frac {12 \ L}{20\ L} *100

\% \ yield= 0.6*100

\% \ yield= 60

For this reaction, the percent yield is 60%.
