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...
knowing how to calculate factors of a number is extremely crucial in maths. the steps to find the factors of a number are given below in a very easy to understand way. an example is taken to make the explanation easier. find the factors of 16. step 1: write the numbers from 1 to ...
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...

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
21%=massingofNaCl100mLoftotalsolution×100% Solving for the mass of solute you find: 21=massingofNaCl This means that there are 21 grams of NaCl in every 100 mL of solution. To find molarity you will need to convert this number of grams into moles by using the molar mass of NaCl: 21...
