How to Calculate Equivalent Weight Equivalent Weight Examples Lesson Summary Frequently Asked Questions What is the equivalent weight of NaOH? To determine the equivalent weight of NaOH, first it needs to be determined what type of substance it is. NaOH is a base; therefore, the n number of ...
As we know, Equivalent weight = molecular weight/number of H+ replacedSo, in H2SO4, E = M/2 = 98/2 = 49g/equivalent of H+ 1. But in this reaction, NaOH + H2SO4 = NaHSO4 + H2O how to calculate the equivalent weight of H2SO4?2. 2NaOH + H3PO4 = Na2HPO4 + H2O, How to...
How To Calculate Equivalent UnitsScience ChemistryHow To Calculate Equivalent UnitsBy Rosann Kozlowski Updated Aug 30, 2022 photongpix/iStock/GettyImages Chemists use equivalent units, or equivalents, to express the reactive capacity of a chemical species such as electrons or ions. The number of...
Now, you can tackle the question at the beginning of the article. Say you need to make 1 L of a 1M NaCl solution. How do you know how much salt to weight out? First, you will need to find the number of moles you need for this solution. To do this, you will need to make use...
Molarity (M) = (moles of solute) ÷ (liters of solution). To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. Yo...
Given the molecular weight of NaOH is 40, answer the following question: How much NaOH do you need to make 200 ml of 0.5 M NaOH solution? If I have 1 liter of a 1M solution of HCl, how many grams of NaOH must I add to neutra...
Now that we know what these numbers mean, we can calculate the overall diameter of a tire. We multiply the tire width by the aspect ratio to get the height of the tire. Tire height = 235 x 75 percent = 176.25 mm (6.94 in) Then we add twice the tire height to the rim diameter. ...
Calculate how much glucose is needed to make 500 mL of a 5% glucose solution. Solutions: In chemistry, a solution is created by dissolving a substance *the solute) in another substance (the solvent). For example, when we mix table salt (NaCl) with water, we are effect...
Calculate the compound’s molecular weight using the atomic weights provided in the periodic table of the elements. Multiply the number of each type of atom by its molecular weight and then sum the products. In the case of aspirin, the molecular weights of carbon, hydrogen and oxygen are 12.0...
Calculate the gram weight of the solute to make 1 liter of solution. You can calculate gram weight from the given molarity of the solution using the formula MW X molarity. A 2M solution of sodium chloride requires 58.4 grams X 2M, or 116.8 grams in 1 liter. ...
