Henry law:
P = KC
P = solvent vapour pressure
K = Henry constant
C = conc of solute
So, 0.2 = 773 C
so, C = 0.2 / 773 = 2.5 x 10^{-4} molal
Which atom?
Atomic mass - proton
Answer:
The correct answer is c) polar
Explanation:
Water is a polar chemical compound, formed by the covalent bond between hydrogen and oxygen. There is an electronegative region on the part of the latter and an electropositive one on the part of hydrogen. Each molecule forms a Hydrogen Bridge junction with the oxygen atom of another nearby molecule.
