Solve each problem involving the basic properties of thermodynamics and fluid mechanics. Write your complete solution on a separate sheet paper. Use two decimal places for your final answers.

Note: Use the table of standard atmospheric pressure for the conversion of the pressure units

Problem 1: Two liquid substance with different densities are mixed to form a solution with a resulting specific volume of 0.9 L/kgm. Substance A has a specific gravity of 1.8 while substance B has a specific gravity of 0.8. A container with a volume of 135 liters was filled with these solution. Calculate the mass of each substance in kilograms and the weight of the solution in kgf
