Percentage yield is worked out as (amount you got/ amount you could have got) x 100 You should do the calculation in moles so weigh your compound, work out its molar mass and divide the mass by the molar mass to get number of moles. Then you have to work out your maximum theoretical yield - work out how many moles of reactant you started with and check the stoichiometric ratio from your balanced equation to find how many moles you expected to get. In organic reactions a yield of 60% or so is normal. The more steps you went through in your preparation, the lower you would expect your yield to be. Many reactions just do give a low yield anyway, because they are at equilibrium rather than going to completion, like the Haber process.

An unknown sample with a molecular mass of 180.0g is analyzed to yield 40 percent C 6.7 percent H and 53.3 percent O What is the empirical formula and the molecular formula of this compound?
ch2o and c6h12o6
How is percent yield caculated?
Percent yield = (actual yield/expected yield) x 100
What is percentage error in a chemistry experiment?
(actual yield-theoretical yield) / (theoretical yield)
Why do the theoretical and practical values differ?
Theoretical yield is what you have calculated to be your end result of product, usually in mass. Actual yield is what you experimentally were able to produce. Together they are used to determine percent yield.
Dividing the actual yield by the theoretical and multiplying it by 100 is called?
calculating the percent yield.
What is the Formula for percentage yield?
Percentage yield = (Actual yield / Theoretical yield) x 100% The percentage yield for a reaction is a value between 0 to 100 percent.

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 :)
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
What a chemistry word that starts with y?
yield
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
