1 Mole of NaOH weighs 40.01 grams (23.0 g Na + 16.0 g O + 1.008 g H) 15.55 grams NaOH X (1 mole NaOH/ 40.01 grams NaOH) = 0.389 moles NaOH 500.0 mL X (1.0 Liter/1,000 mL) = 0.500L solution 0.389 moles NaOH/0.500L solution = 0.780M solution ...
Okay, so I have a quick question about a problem in my lab. The question is: Calculate the number or moles of atoms of magnesium ribbon used. Now...
Molalityis the number of moles of solute per kilogram of solvent. Because the density of water at 25°C is about 1 kilogram per liter, molality is approximately equal to molarity for dilute aqueous solutions at this temperature. This is a useful approximation, but remember that it is only an...
Using a standard state in which there are 1,000 g of water (55.51 moles) per 1,000 cm 3 of solution allows activity of water in a NaCl solution at high temperature to be closely approximated by the effective density of water, p e, in that solution, i.e. the product of the density...
How To Calculate Mass of Solute in Solution?Step 1: Mass of a solute is calculated by using molarity. It is most often method used in chemistry. The equation for calculating molarity is:Molarity = MolesofsoluteLitresofsolutionWith the help of the above formula, if we know the molarity (con...
A good volume of NaOH to use per titration is 15 mL. From this molarity and volume, the moles of N Explain what is meant by the equivalence point in the titration of HCI solution with NaOH solution. Which of the following titrations wil...
