| mols | concentration | volume | |
| 0.254 molls | 0.212 M | 1.2 liters | |
| 0.305 mols | 0.254 M | 1.2 L | |
| 0.254 mols | 1.2 M | 0.212 L |
use formula
mols = concentration x volume
concentration = mols/volume
volume = mols/concentration

SUTULIUTIS Exercise D Calculating Molarity Concentration (1 pt per answer, 10 total) Complete the following table by calculating the molarity for the following solutions. The molarity is the number of moles of the solute divided by the volume of the solution in Liters. Use the molecular mass of the solute to calculate the moles if you only have the mass of the solute. Fill in all of the empty columns. The volume must be in Liters. Mass of solute Moles...

Dilution of Concentrated Solutions The number of moles of solute in liters of a solution of molarity is given by Moles Solute = m x v It is often of practical importance to take a concentrated solution of known concentration, and to add solvent to it to obtain a diluted solution with a desired concentration. During the process of dilution, since only solvent is added, the number of moles of solute is constant. Using to denote the concentrated solution, and...

Given the equation: 3A(aq) + 2B(aq) = 3C(aq) + 2D(aq) When 45.0 mL of 0.050M do A in mixed with 25.0 mL of 0.10M of B, the concentration, at equilibrium, of C was found to be 0.021M and D at 0.014M. Calculate Kc. {Tip: Moles of A that reacted = moles of C thats produced and moles of B that reacted = moles of D produced at equilibrium. From their molarities, use the total volume of the mixture. number of...
