The picture shows a great deal of cocoa mix on the surface. suppose that no more cocoa can be dissolved. the solution has reached

Explanation:

A saturate is a solution which contains maximum amount of solute. So, when we further add solute into the solvent then solute is not able to dissolve in it and remains in its powdered or original form.

And, this point is known as saturation point and the solution is known as saturated solution.

A saturated solution is also able to conduct electricity.

Thus, we can conclude that in the given picture when no more cocoa can be dissolved. The solution has reached to its saturation point.

i just got this problem. it's 90.3

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
