You have a beaker with a measured 10mL of HCl (unknown Molarity) which you weigh the solution as 10g. You need to find out the mass of the solvent. Ultimately, I need to determine the Molarity of the solution but I need themass of solvent(the water in the HCl solution) to determine ...
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 of a liquid and the volume of the liquid, you can calculate its mass. Similarly, if you know the mass and volume of a liquid, y...

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 of the solute is needed, which can be found on certainperiodic tables. Molar massof K = 39.1 g Molar mass of Mn =...
Moles and Molarity For acid-base chemistry purposes, it is more appropriate to measure solute concentration in moles, or individual particles (e.g., atoms, molecules), per unit volume rather than mass per unit volume. This is because atoms react with each other in known proportions in a way...
Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean. Leant how to find the mean here.
To find the molar mass of a compound, you need to add the molar mass of all the elements in that compound. Take a look at NaOH which contains sodium, oxygen and hydrogen. The molar mass of sodium is 22.99 g/mol, oxygen is 15.999 g/mol, and hydrogen is 1.008 g/mol. ...

number of factors product of factors sum of factors let us assume n is a natural number, for which we need to find the factors. if we convert n into the product of prime numbers by prime factorization method, we can represent it as; n = x a × y b × z c where x, y ...
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...
