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...
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 ...
3. Calculate Molarity Divide the number of moles of NaCl by the volume of the solution to get molarity. 0.21 moles ÷ 0.59 liters = 0.356 M. References Royal Society of Chemistry: Periodic Table ThoughtCo: What Is a Mole in Chemistry?

We calculate the theoretical yield by taking the given mass of the reactants and multiplying it by the molar mass of the reactants and the molar mass of the products. The unites will cancel out and leave grams in the end. What does the percent yield tell you? The percent yield is the...
What is conductometric titration in analytical chemistry? In a titration of a sample of HCl(aq) with 0.113 M NaOH(aq), it took 51.2 mL of the base to reach the endpoint of the titration. Calculate the number of moles of the acid being neutralized. ...
AVERAGE function - calculate an average of numbers You use the Excel AVERAGE function to get an average of all numbers in the specified cells or ranges. AVERAGE(number1, [number2], …) Wherenumber1,number2, … are numeric values for which you want to find the average. Up to 255 argumen...
Learn how to calculate the concentration of a solute in grams per liter, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.
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 ...
