Converting 0.1o g NaCl to moles, we have 0.1o g / 58 g/mol = 0.0017 moles Converting 1.0 ml of solution to liters (L) we have 1.0 ml /1000 ml/L = 0.0010 L Dividing moles by liters to get molarity (M) we have 0.0017 moles / 0.0010 L = 1.7 M Upvote • 0 Down...
Molar Mass of HCl: 36.46 g/mol ElementSymbolAtomsMass % Hydrogen H 1 2.8% Chlorine Cl 1 97.2% While molarity is usually a convenient way to talk about concentration, sometimes there aren't actually that many moles in the solution. What does that mean? Well, say you have a 0.001 M so...

Calculate the molarity of the acetic acid in vinegar, if a 500ml sample of the vinegar requires 43.50 ml of 0.105 M NaOH to reach a phenolphthalein endpoint in a titration. What is the indicator in the titration with permanganate solution?
Example: What is the molarity of a solution of 6 grams of NaCl (~1 teaspoon of table salt) dissolved in 500 milliliters of water? First, convert grams of NaCl to moles of NaCl. From the periodic table: Na = 23.0 g/mol Cl = 35.5 g/mol ...
To go from molarity to pH, use your calculator or a similar tool to take the logarithm to the base 10 (the default base) of the molarity, reverse the sign to get a positive value, and you're done! Example: If the molarity of an aqueous solution is 6.3 × 10-5 M, what is the ...
To find the molarity, you can divide the number of moles by the volume of the solute (in liters): \(\mathrm{\dfrac{0.36mol\enspace NaCl}{0.1L}=3.6M\enspace NaCl}\) This means that a 21% w/v solution of NaCl is the same as a 3.6 solution of NaCl. In this way, you can co...
What Is Molarity? Concentration in moles per liter (mol/L) is calledmolarity,denoted M. You were told above that in chemical reactions, atoms combine in terms of moles, which you now can get from their masses. For example, in a calcium chloride (CaCl2) solution, the dissociation reaction ...
How to find molar mass from titration? What is the molarity of NaOH if it takes 40.0 mL of NaOH to reach the equivalence point in a titration with 50.0 mL of 0.2 mol/L HCL? (A: 0.25M) The point in a titration where the moles of acid are ...
