For chemistry and other sciences, it is customary to keep a negative value, should one occur. Whether error is positive or negative is important. For example, you would not expect to have a positive percent error comparing actual totheoretical yield in a chemical reaction. If a positive value...
The percent yield tells us how much of the product could have possibly been lost to human errorCalculation of Theoretical Yield In chemistry terms we refer to yield as the quantity of product that can be produced from a reaction. Theoretical yield is the maximum amount of product that could ...
If you see "normal" as "expected," even in the chemical sense this is more or less on target: A normalized preparation is one that has been created in proportion or relation to an established standard. To discover how to calculate the normality of NaOH, or how to convert from normality ...
if the per cent error is very low you can neglect it but if the per cent error is high you have to calculate or measure the things again to get the absolute

The INDIRECT function finds all scores in Chemistry, the AVERAGE function calculates the average scores. Use the Fill Handle to copy the formula. 1.4. Determining the Average with Criteria A student obtains 0 and you need to ignore the 0. To calculate the average of scores greater than 0: ...
Convert the volume to m3. Divide the mass by the volume. You will then have the density of the object in units of kg/m3. How do I calculate the density of the Earth? Note the mass of Earth in kilograms, which is 6×1024 kg. Look up the volume of the Earth in m3, which is ...
Over the years chromatography has gained an enviable position in analytical laboratories. You have been introduced to simple concepts on how to read a chromatogram.
