Asolution contains 90 ml of methanol, 18 ml of propanol, and 2 ml of diethyl ether. which is the solvent in this solution? -methanol. -propanol. -diethyl ether. -water

The solvent is the substance in which the solute is dissolved. The solvent is considered the substance that is present in larger quantity in a solution. The others are the solute. In this solution you should consider that propanol and diethyl ether are both dissolved in mehtanol. So, in this solution methanol is the solvent, while propanol and diethyl ether are solutes.

Methanolpropanoldiethyl etherwater
A is the answer

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
