Here is the equation to use when calculating w/v percent for a solution: w/v%=massingofsolutevolumeinmLoftotalsolution×100%Making Solutions of a Given Concentration So then, if you were asked to make 100 mL of a 17% w/v solution of sodium azide, how would you do this? You can make...
How to Calculate the Concentration of a Solute in Grams per Liter Step 1: Identify the mass of the solute. Step 2: Identify the volume of solution. Step 3: Divide the mass of the solute by the volume of solution to find the concentration of the solution. How to Calculate...
If you don't know the concentrations of your initial solutions, calculate molarity by dividing the number of moles in a solute by the volume of the solution in liters. For example, the molarity of a 0.6 moles of NaCl dissolved in 0.45 liters is 1.33 M (0.6 mol ÷ 0.45 L). Do this...
My attempted answer is below: I'm struggling to find the mass. Is the mass 50.0mL + 25.0mL = 75.0mL solution It says to assume 1mL solution = 1g solution Is this referring to the solution or just the water? If it is referring to the solution, would the mass be 75.0g? q(soln)=...
To calculatemolarity: Find the number of moles of solute dissolved in solution, Find the volume ofsolutionin liters, and Divide moles solute by liters solution. Make certain to use the correct number of significant figures when reporting your answer. One easy way to track the number of signif...
Example: Phil weighs 155 pounds. To calculate the volume of his body, divide by the average density of the human body in pounds per gallon: 155pounds1gallon8.3pounds=18.41gallons=2.43cubic feet=0.07cubic meters References Phil Plait's Bad Astronomy: Floating in Water ...
The volume of a cylinder of radius r and height h is V = πr^2h. Learn the formulas for the volumes of different types of cylinders along with a few solved examples.
Use this formula to calculate ionic strength: I= 1/2 n∑i (CiZi )squared, where "I" represents ionic strength, "n" represents the number of ions in solution, "i" represents the specific ion in solution, "Ci" represents the concentration to the /th species, such as moles per liter,...
If the mass of nail used was 1.45g, calculate the number of moles of Fe2+ produced in the reaction.The solution they gave was simple:5 x (4 x 10-4) x 10= 0.02 mol.But I don't understand. If 1 mol of MnO4 requires 5 mol of Fe2+, wouldn't it mean that 1 mol of Fe 2+ ...
