Each water molecule consists of two atoms of the element hydrogen joined to one atom of the element oxygen. An interesting property of water is the ability of its molecules to “stick together.” This occurs because one side of each water molecule is slightly negative and the other side is slightly positive. The positive portion of a water molecule is attracted to the negative portion of an adjacent water molecule. As a result, water molecules are called polar molecules. They attract other water molecules like little magnets. It is most likely ionic bonding but between hydrogen and oxygen it is covalent.

Hey there!:
Molar mass benzene = 78.11 g/mol
find number of moles of benzene :
Moles of benzene = mass / molar mass of benzene
Moles of benzene = 94.0 / 78.11
Moles of benzene = 1.203 moles
Molar mass camphor = 152.23 g/mol
Moles of camphor = 26.6 / 152.23
Moles of camphor = 0.1747 moles
Therefore , vapor pressure of solution is :
mole fraction of benzene * vapor pressure of solution
= 1.203 / ( 1.203 + 0.1747 ) * 100.0
= ( 1.230 / 1.3777 ) * 100.0
= 0.8927 * 100.0
=> 89.27 mmHg
Hope this helps !
