A solution contains 42.5 g of heptane ($C_7H_{16}$) and 44.0 g of octane ($C_8H_{18}$) at 25 $^\circ$C. The vapor pressures of pure heptane and pure octane at 25 $^\circ$C are 45.8 and 10.9 torr, respectively. Assuming ideal behavior, calculate each of the following. What is the mass percent concentration of heptane in the vapor phase? Express your answer in percent to three significant figures. mass % heptane = 50.01 % Incorrect; Try Again; 2 attempts remaining Part E What is the mass percent concentration of octane in the vapor phase?

QUESTION 4 Given that the function $y_1 = e^{2x}$ is a solution of the corresponding homogeneous equation $(x+2)\frac{d^2y}{dx^2} - (2x+5)\frac{dy}{dx} + 2y = (x+1)e^x$, use the method of reduction to obtain the general solution of the nonhomogeneous equation.
