Question

liquid a is known to have a higher vapor pressure and higher viscosity than liquid b. use these facts to predict the result of each experiment in the table below, if you can. experiment predicted outcome 500. g samples of liquid a and liquid b are weighed out, and the volumes $v_a$ and $v_b$ of the samples are measured. $v_a$ will be greater than $v_b$ $v_a$ will be less than $v_b$ $v_a$ will be equal to $v_b$ its impossible to predict whether $v_a$ or $v_b$ will be greater without more information. 45.0 ml of liquid a are put in one sealed 5 l flask, and 45.0 ml of liquid b are put in another sealed 5 l flask. the pressure in each flask is slowly increased by pumping in argon gas. eventually both liquids boil, a first and then b. eventually both liquids boil, b first and then a. neither liquid will boil its impossible to predict whether either liquid boils without more information.

Explanation:

Step1: Recall density - mass - volume relationship

Density $
ho=\frac{m}{V}$, so $V = \frac{m}{
ho}$. Given mass $m_A=m_B = 500\ g$. But we have no information about the densities of Liquid A and Liquid B. Vapor - pressure and viscosity do not directly relate to density.

Step2: Analyze boiling - point situation

Boiling occurs when the vapor - pressure of a liquid equals the external pressure. Increasing the external pressure by pumping in argon gas will change the boiling - point. However, we only know the relative vapor - pressures at a given condition, and we don't know the relationship between the vapor - pressure and the external pressure increase for each liquid.

Answer:

It's impossible to predict whether $V_A$ or $V_B$ will be greater without more information.
