A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).
The specific gravity or relative density of a substance is the ratio of its density to the density of a reference material. The relative density of the concentrated salt solution is 1.044.
Mathematically;
Density of the concentrated salt = mass of salt/volume of salt = 5.222 g/5.000 mL = 1.044 g/mL
In the case of specific gravity, the reference material is always water and water has a density of 1 g/mL.
Hence, specific gravity of the concentrated salt solution =
Density of concentrated salt solution/density of equal volume of water
= 1.044 g/mL/1 g/mL
= 1.044
Note that specific gravity is dimensionless.

I think that it is D because the higher the molecular mass, the higher it's boiling point. I hope that helped:) Bye!
Explanation:
Osmosis is the movement of water molecules, across a semipermeable membrane, from a hypotonic solution to a hypertonic solution
Osmosis is critical in the maintenance of the right amount of water in the cells an organism. Water is a universal solvent and is especially important for biochemical activities of a cell. Osmosis maintains the right water homeostasis in cells.
Osmosis is useful in the absorption of water by the roots of the plants and the maintenance of transpirational pull that ensures herbecious plants remain upright.
Osmosis enables the opening and closing of plant stomata hence regulating the loss of water by the plants.
