There are several reasons why you may not receive a 100 percent yield of a product. The reaction may have been incomplete, your reactants may have been impure, and the product can also be lost during filtration or similar processes.

∙ 10y agoA 100% yield represents perfect conditions. That said, we all know nothing can be perfect. Errors and limitations in measurement, contamination of reagents, and reactions not going to completion can all result in lower yields. A 50% yield actually isn't too bad.

A very simple and common process is making methanol from carbon monoxide and hydrogen by the formula:
CO + 2H2 = CH3OH
So you need two moles of hydrogen molecules for every mole of carbon monoxide, and you know there's no way you will ever get exactly this ratio in your reactor. So you introduce a surplus of hydrogen--unlike carbon monoxide, no one ever died from inhaling hydrogen.

What is the percent yield for carbon disulfide if the reaction of 40.0g of carbon produces 33.0g of carbon disulfide?
This yield is very low - 13 %.
How is percent yield caculated?
Percent yield = (actual yield/expected yield) x 100
Dividing the actual yield by the theoretical and multiplying it by 100 is called?
calculating the percent yield.
Is an ilmenite with 7 percent titanium oxide good?
No - that is low yield - there are ores richer than that around the world
Is experimental yield the same as percent yield or actual yield?
The percentage yield is the Actual Yield divided by the Theoretical Yield, all multiplied by 100. Percentage = [(Actual)/(Theoretical)] x 100
What is the percent yield for carbon disulfide if the reaction of 40.0g of carbon produces 33.0g of carbon disulfide?
This yield is very low - 13 %.
How is percent yield caculated?
Percent yield = (actual yield/expected yield) x 100
What are some fruits and vegetables with very low yield percent?
grapefruit, watermelon, hard squashes
Dividing the actual yield by the theoretical and multiplying it by 100 is called?
calculating the percent yield.
How do you find 85.0 percent in percent yield?
if you received 85.0 percent back from your product then your percent yield is 85 percent.
What is the percent yield of 122 grams of product?
If this is the actual yield, real amount produced, then you need the theoretical yield to find the percent yield. % yield = (actual yield / theoretical yield) x 100
If the actual yield of Mg3N2 is 47.87 g and the theoretical is 50.26 g What is the percent yield?
Percent yield = Actual Yield / Theoretical Yield * 100 hope that helps :)
Is an ilmenite with 7 percent titanium oxide good?
No - that is low yield - there are ores richer than that around the world
What if i don't know the yield percent?
Do you need it? Are you being told to calculate it? percent yield = (actual yield) divided by (theoretical yield) x 100
Is experimental yield the same as percent yield or actual yield?
The percentage yield is the Actual Yield divided by the Theoretical Yield, all multiplied by 100. Percentage = [(Actual)/(Theoretical)] x 100
When 320g octane C8H18 is burned in oxygen 392g of water is recovered what is the percent yield of the experiment?
the percent yield be the actual yield (392) divided by the theoretical yield (i calculated 450). 392/450 equals .87 multiply by 100 and the percent yield is 87%.
What does the conventional symbol LY on a topographic map mean?
