What is the molality of solution?
The number of moles of a solute per kilogram of solvent. (Apex)
What is the total number of moles of solute in 2.0 liters of 3.0 M NaOH?
I believe the molarity is 1. molarity = number of moles / liters of solution molarity = 3 / 3 = 1
Why did chemists develop the concept of molarity?
It helps to quantify the concentration of solute in any solution - molarity is calculated by dividing the amount of solute by the total volume of the solution. The unit of molarity is moles/L.
The number of moles of solute divided by the number of liters of solution equals?
Molarity = Mols of solute / L of solution total
What is the definition of Analytical molarity?
The total number of moles of a solute, regardless of state, in one liter of solution. Given as moles/L.

What is the molarity of a solution with 0.207 mol of calcium acetate dissolved in a total volume of 166.5mL?
Molarity = moles solute/liters solution = 0.207 moles/0.1665 L = 1.24 molar (3 sig. figs.)
What is dilute solution and concentration?
A dilute solution is a solution in which there is a small amount of solute (the thing that gets dissolved) compared to the total amount of possible solute that can be dissolved in the solvent (the thing that does the dissolving). A concentrated solution is when there is a lot or all solute that can possibly fit in the solvent.
What is one advantage of percentage over molarity as a measure of solute concentration?
Concentrations in molality (moles of solute per kilograms of solvent) are independent of temperature and pressure whereas concentrations in molarity (moles of solute per total volume of solution in liters) are not.
What are three ways you can measure concentration?
The three main ways are: molarity (M) = moles solute/liters solution; molality (m) = moles solute/kilograms solvent; mole fraction = moles 1 component/total moles all components. There's also percent by volume, percent by mass, and normality.
300.0 Ml of water is added to .40 L of a .400 M Na2CrO4 solution what is the molarity of the resulting solution?
300.0 ml of water is added to .40 L of a .400 M Na2CrO4 solution what is the molarity of the resulting solution? Na2CrO4 = 2 Cr +Cr + 4 O's Molar mass = (2*23 + 52 + (4*16) = 162 A .400 M N Na2CrO4 solution has .400 moles of Na2CrO4 in a liter of water. .400 moles of Na2CrO4 = 0.400 * 162 = 64.8 grams of Na2CrO4 in a liter of water. Since you only have .40 L, you have 64.8 grams/liter * 0.4L = 25.92 grams of Na2CrO4 in 0.4 liter of solution. When you add 300.0 ml of water, you have total of 700 ml of solution. You still have 25.92 grams of Na2CrO4, but now you have 700 ml of solution. Molarity = moles of solute per liter of solution. Moles of solute = grams of solute ÷ Molar mass of solute Moles of solute = 25.92 ÷ 162 = 0.16 moles of Na2CrO4. Molarity = 0.16 moles of Na2CrO4 ÷ 0.700 L of solution. Molarity = 0.23 M
750 ml of 20M HCl is mixed with 250 ml of 60M HCl What is the new molarity?
Molarity of a solution is the number of moles of the solute divided by the volume of the solution (in liters). If 750 ml of 20M HCl is mixed with 250 ml of 60M HCl, we first find the total number of moles of HCl in our new solution. Using that same formula, M=moles/V, we cansee that moles=MV. In the first solution we have (20M)(0.750L) = 15 moles. In the second, (60M)(0.250L) = 15 moles, so we have a total of 30 moles in our new solution, which also has a volume of 750mL + 250mL = 1L. The molarity of the new solution is 30 moles/1L = 30M
What is the molarity of a solution of lii which contains 26800 mg of solute in a total volume of 0.282l?
0.0296 M solution means 1000 ml contains 0.0296 moles of LiI By applying unitary method we get, no. of moles of LiI in 258.6ml =.00765456 moles
