Uploaded on Jun 13, 2011Step by step directions for calculating the percent error after a density lab. For this calculation you will need to look up the density what is a good percent error of the substance that you tested in the lab to use for the actual or true value.

The mass of the element is 10.23 g The volume of the water it was placed in was 20.0 mL The volume of the water after the element was placed in it was 21.5 mL b) If the accepted value is 6.93 grams per milliliter, calculate the percent error in significant figures. 1 following 5 answers 5 Report Abuse Are you sure https://answers.yahoo.com/question/?qid=20100116125458AA0ZwAq you want to delete this answer?

Trending Now Conor McGregor Philip Rivers Wiz Khalifa Tim Tebow Miranda Lambert Luxury SUV Deals Kevin Meaney Oregon Ducks Rheumatoid Arthritis Symptoms 2016 Cars Answers Relevance Rating Newest Oldest Best Answer: Density is mass/volume. You're given a mass of 10.23 g, and based on the amount of displaced water the volume of the element is 1.5mL. So: 10.23/1.50 = 6.82g/mL. (6.82/6.93)*100=98.4% yield, or 1.6% error.

Take your estimate of what it should be, then subract the estimate from the actual number. divide this by the actual number, and multiply by 100. Doesn't matter if it's negative, just make it a positive. ie. Estimate = 200, Actual = 150 200-150=50 50/150=.333 .333 * 100 = 33.3% Smiley Faced · 7 years ago 0 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Report Abuse To find the density you use th
| Scientific Calculator | Statistics Calculator In the real world, the data measured or used https://socratic.org/chemistry/measurement-in-chemistry/accuracy-precision-and-percent-error is normally different from the true value. The error comes from the measurement inaccuracy or the approximation used percent error instead of the real data, for example use 3.14 instead of π. Normally people use absolute error, relative error, and percent error to represent such discrepancy: absolute error = |Vtrue - Vused| relative error = |(Vtrue how to calculate - Vused)/Vtrue| (if Vtrue is not zero) percent error = |(Vtrue - Vused)/Vtrue| X 100 (if Vtrue is not zero) Where: Vtrue is the true value Vused is the value used The definitions above are based on the fact that the true values are known. In many situations, the true values are unknown. If so, people use the standard deviation to represent the error. Please check the standard deviation calculator.

Post More videos Key Questions What does accuracy in chemistry mean? If a measurement is accurate, that means that it's close to the actual value of the thing being measured. For example, if my cat weighs 6500 grams and a scale said it weighed 6400 grams, this measurement would have moderately good accuracy. OK. misterguch · 1 · 1 comment · Jul 3 2014 How can precision be measured? To measure precision, just measure something a whole bunch of times with some measuring tool. If you get the same answer every time, you've got a precise measurement. Typically, precision manifests itself in the number of significant figures present in a measurement. If a balance can read the mass of something to 1.488 grams, we assume that it's precise to the nearest 0.001 gram. This may or may not actually be the case. misterguch · 1 · 4 comments · Mar 24 2014 Why is percent error important? Percent error tells you how badly things went wrong. Here's the deal: Whenever you do an experiment, things go wrong - that's true for anybody no matter how good they are. Things get spilled, things are impure, equipment is imprecise... you get the idea. No matter who you
