Molarity (M) = (moles of solute) ÷ (liters of solution). To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. Yo...
First, you will need to find the number of moles you need for this solution. To do this, you will need to make use of the desired molarity and the volume of desired solution. (1mol1L)(1L)=1mol This calculation means that you need one mole of salt. Now, you need to use the mola...

What volume (L) of an aqueous solution that is 24.00% by mass ammonia (NH3) and has a density of 0.910 g/mL must be taken to obtain 61.2 g of ammonia (NH3)? Calculate the molarity of a 6% solution of ammonium nitrate of density 1.025 g/mL....
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. ...

Molarityis one of the most common units of concentration. It is used when the temperature of an experiment won't change. It's one of the easiest units to calculate. You get the mass of solute for the solution, mix the solute with a known volume of solvent, and divide mass by volume ...
