Question

Calculate the volume ( L ) of the solute H2O and thevolume ( L ) of the solvent (CH3)2CO thatshould be combined to generate 9.20 kg of a solution that is 1.66 mH2O.

volume ( L ) of the H2O

volume ( L ) of the(CH3)2CO
Molar Mass (g/mol) H2O 18.015 (CH3)2CO 58.05 Density ( kg/L ) H2O 0.9982 (CH3)2CO 0.7899 Name/Formula water H2O acetone (CH3)2CO Calculate the volume ( L ) of the solute H2O and thevolume ( L ) of the solvent (CH3)2CO thatshould be combined to generate 9.20 kg of a solution that is 1.66 mH2O.

volume ( L ) of the H2O

volume ( L ) of the(CH3)2CO
Molar Mass (g/mol) H2O 18.015 (CH3)2CO 58.05 Density ( kg/L ) H2O 0.9982 (CH3)2CO 0.7899 Name/Formula water H2O acetone (CH3)2CO

Explanation / Answer

Required a 1.66 m H2O containing 9.2 kg solution.

1.66 molal means 1.66 moles of water in 1 kg of solution.

So in 9.2 kg, moles of water = 1.66 *9.2 = 15.27 moles
