What is the molecular weight, density, and how many moles in
1) 1ml of water
2) 0.04 g of benzophenone

1)

2)

Explanation:

Hello,

In this case, the molar mass is obtained by adding each atom's atomic mass multiplied by the number of atoms in the molecule, the density is searched on databases and the moles by using a dimensional analysis with the molar mass starting by the compound's mass, thus, for each case, we obtain:

Best regards.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
