PV = nRT (note: change temp of 100C to 373 K) V = nRT/P = (0.34 mol)(0.0821 Latm/Kmol)(373K) / 15 atm = 0.69 liters do the others the same way. Convert grams of material to moles by using the molar mass and then use the moles to find volume using PV = nRT just as in...

Calculate the volume required to obtain 1.20 moles of K2SO4 from a 1.00 M K2SO4 solution. Concept of Molarity: The molarity of a solution is a measure of the concentration of the solute in the solution. The molarity of a solution with a single solute dissolved in ...
Calculate concentration in millimolars using the formula: Molarity (millimolars)= Amount (in millimoles)/Volume of solution (in liters). In our example, the volume of the solution is 500 ml or 0.5 liters. The molarity of NaOH would be: Molarity (NaOH)= 12.5 millimoles/0.5 liters=25 mi...
The science world is filled with different ways to express the vital concept of concentration, which is the amount of something present per unit volume. This "amount" often has units of mass but can include virtually anything that can be quantified: gas particles, photons and more. The volume...

Step 1: Calculate the number of moles of H2SO4We have 400mL of 1200MH2SO4. Moles of H2SO4=Concentration×Volume=1200mol/L×0.4L=0.002mol Since H2SO4 can donate 2 protons (it is a diprotic acid), the number of moles of H+ from H2SO4 is: Moles of H+ from H2SO4=2×0.002mol...
Calculate the volume in milliliters of 1.61 M potassium hydroxide that contains 47.4 g of solute. Calculating volume from given Molarity Here, the problem asks to solve for volume. By simple multiplication of equivalent ratios from the given value, one can get the vol...
Calculate Molarity: moles solute per liter of solution (notvolume of solvent added since the solute takes up some space) symbol: M M = moles / liter Example: What is the molarity of a solution of 6 grams of NaCl (~1 teaspoon of table salt) dissolved in 500 milliliters of water?
moles of KMnO4= 0.15 moles KMnO4 Now the liters of solution is needed. Keep in mind, this is the total volume of the solution, not the volume of solvent used to dissolve the solute. This example is prepared with "enough water" to make 750 mL of solution. ...
