If M is the molar concentration of
, n is the number of moles and V is the volume of the solution:
Answer:
Vapor pressure of the solution is 22.9 torr at 25°C
Explanation:
When a non volatile solute is added to a pure solvent, the vapour pressure of the mixture decrease regard to the pure solvent following the equation (Raoult's law):
Where vapour pressure of the pure solvent (Water) is 23.8torr at 25°C.
Mole fraction of water is the ratio between moles of water and total moles in solution. The solution has a mole fraction of water of:
Replacing in Raoult's law:
<h3>Vapor pressure of the solution is 22.9 torr at 25°C</h3>
Answer:
See explaination
Explanation:
We can describe An electrolyte as a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water.
The anode of a device is the terminal where current flows in from outside. The cathode of a device is the terminal where current flows out.
