The pH scale ranges from 0 to 14 under usual conditions and measures the acidity of an aqueous solution. This is derived from the molarity of protons (hydrogen ions, or H+) in the solution. To find pH for a given molarity, you need to know how to work wi
Calculate the molarityof a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. To convert grams to moles, the molar mass ...
Review how to calculate the mass of a liquid from its volume and density. Density is mass per unit volume: density = mass / volume You can rewrite the equation to solve for mass: mass = volume x density Densityof liquids usually is expressed in units of g/ml. If you know the density...
First, begin by converting millimolar to molar: (10mmolMgCl21L)(1mol1000mmol)=0.010molMgCl21L Next, you can use the molar mass to find how many grams of MgCl2 there are in 0.010 moles or MgCl2. (0.010molMgCl21L)(96.211gMgCl21molMgCl2)=0.962gMgCl21L Finally, you can convert the number...

If a titration of 0.5533 grams of KHP needs 25.84 mL of a NaOH solution to reach the equivalence point, what is the concentration of the NaOH? How to find molar mass from titration? What is the molarity of NaOH if it takes 40.0 mL of NaOH to...
What will be the molarity of the resulting solution? How much water will you have to add to make a 1 M solution from the solution produced? How many grams of KMnO_4 (molar mass = 158.034 g/mol) is needed to make 400.0 ml of a 0.400 m solution? What mass...
Convert grams of water to volume of water using density (1.00 g/mL) Now divide moles of solute by litres of water to get molarity, except, it’s not quite right unless, as I stated in the first sentence, the volume of water is the volume of solution, which it isn’t but in dilute...
The conversion from kg to mg takes two steps: {eq}kg\rightarrow g\rightarrow mg {/eq} The respective conversion factors are: {eq}1\;kg=10^{3}\;g\r...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can ...
