Find the molarity of a solution that is made by dissolving 76.54g NaCl in enough water to make a 3,567 mL solution. Calculate the pH of a buffer solution prepared from 0.155 mol of phosphoric acid, 0.250 mol of KH_2PO_4, and enoug...
Find the molarity of a solution that is made by dissolving 76.54g NaCl in enough water to make a 3,567 mL solution. You want to make 52 mL of a solution with a final concentration of 388 mg/mL. How much solute (g) will you need?
How to Find Molarity As long as you have a way of measuring the mass of a solute, you can calculate its molarity by measuring the volume of the solution. Be careful here, because molarity is always expressed as moles/liter, so if you measure volume in any other units, you have to con...

To find the molar mass of NaCl, you add the mass of each element. Work out 22.9898 + 35.4530 = 58.4538.Moles of Solute Say you create a solution with 200 grams of table salt. One mole equals the molar mass of the solute which is 58.4538 grams. Divide the mass of the solute by the...
Square root of a number gives the original number when multiplied by itself, but if a number is multiplied three times, then we can find the cube root of it. Learn to evaluate here at BYJU's.
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.
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...
Find the molarity of a salt solution made by dissolving 560 mg of NaCl in 4 ml of water? What is the osmolarity of this solution assuming the final volume is the same as the amount of water? Fill in the blank: the area under th...
This example problem demonstrates how to calculate freezing point depression using a solution of salt in water. Key Takeaways: Calculate Freezing Point Depression Freezing point depression is a property of solutions where the solute lowers the normal freezing point of the solvent. ...
