Divide the original moles of chemical in 1 liter of solution by the mass of solution in kg. The result is the molality of the solution, or the moles chemical per 1 kilogram solvent. In this example, the solution concentration is 2.50 moles KCl divided by 0.8636 kg solvent, which is a m...
You can use any units you wish for the concentration values and volumes, so long as you use the same units for each of the two solutions. Concentration can also be expressed by percent composition by mass, mole fraction, molarity, molality or normality. For example, work out the percent co...

Because this is a neutralization reaction, ...
Knowing the solution's molarity, it is easy to find solute's mass in given solution's volume. Answer and Explanation: Given Data: The molarity of the solution is 4.25 M. The volume of solution is 10.0 mL. The molarity is calculated by the formula shown below. {...
How many grams of water must be added to 153 grams of sucrose to produce a solution that is 8.00% (m/m) sucrose? What is the mass percent of sucrose (C_{12}H_{22}O_{11}, Mm = 342 g / mol) in a 0.371 m sucrose solution? Determine the amount of sucrose in ...
How many mL of 6M NaOH would be required to neutralize 1 mL of stock sulfuric acid (assume the stock percent assay is 98%)? A sodium hydroxide solution that contains 50 grams of NaOH per L of solution has a density of 1.13 g/mL. Calculate the molality of the NaOH in this sol...
How do you solve for mole fraction, density and %w/w, when you are given Cr2(SO4)3, with molarity of 1.26 M and molality of 1.37 m? Concentration Units: Both concentration units of molarity and molality are expressed in moles ...
