Why is a volumetric pipette more precise than a measuring cylinder?

Chemistry
1 answer:
Scilla [17]3 years ago
5 0

Volume of liquids are measured in experiments. The volume is measured by taking reading that coincides with the lower meniscus of the liquid. There are several measuring devices used in laboratory such as beakers, measuring cylinders,  volumetric pipets etc. volume measured from volumetric pipets are considered to be more precise than from measuring cylinders because they are simple, and its long neck lowers the chances of error in looking for the meniscus.

What is the percent yield if the quantity of reactants is sufficient to produce 0.86g of
Juliette [100K]

Taking into account definition of percent yield, the percent yield for the reaction is 82.56%.

<h3>Definition of percent yield</h3>

The percent yield is the ratio of the actual return to the theoretical return expressed as a percentage.

The percent yield is calculated as the experimental yield divided by the theoretical yield multiplied by 100%:

percent yield= \frac{actual yield}{theorical yield}x100

where the theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.

Percent yield for the reaction in this case

In this case, you know:

  • actual yield= 0.71 grams
  • theorical yield= 0.86 grams

Replacing in the definition of percent yields:

percent yield= \frac{0.71 g}{0.86 g}x100

Solving:

<u><em>percent yield= 82.56%</em></u>

Finally, the percent yield for the reaction is 82.56%.
