By measuring the equilibrium between the liquid and vapor phases of an acetone (A) - ethanol (E) solution at 57.2 ◦C and 1.00 atm it was found that xA = 0.400 and yA = 0.516. Calculate the activities and activity coefficients for both components in this solution using the Raoult’s law basis. The vapor pressure of the pure components at this temperature are: P ∗ A = 786 torr and P ∗ E = 551 torr. (xA is the mole fraction in the liquid and yA the mole fraction in the vapor.)

answer: c.

explanation:

the answer is b & c i believe : )

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
