The mass of the solution of sugar and water is 120 grams.
Mass is the quantity of matter of a physical body.
The mass of the sugar is given is 20g
The mass of the water is 100 g.
100 + 20 = 120 gram
Thus, the mass of the solution of sugar and water is 120 grams.

The type of chemical bonding in sodium phosphate (Na3PO4) is ionic bonding. This is due to the transfer of electrons from sodium atoms to a phosphate group, forming ions which then attract one another to create a balanced, electrically neutral compound.
The chemical bonding in sodium phosphate (Na3PO4) is classified as ionic bonding. Ionic bonding involves the transfer of electrons from one atom to another, resulting in the formation of ions. This occurs between atoms of different electronegativities, typically a metal and a non-metal. Atoms lose or gain electrons to attain a stable, full outer electron shell.
In sodium phosphate, three sodium (Na) atoms each donate an electron to become positively charged ions (cations). The phosphate (PO4) group accepts these electrons to become a negatively charged ion (anion). The electrostatic attraction between the positive sodium ions and the negative phosphate ion forms the ionic bond. These discrete units assemble in a three-dimensional lattice structure in a way that ensures the overall compound is electrically neutral.

2.) No because hydrogen can only form these bonds with highly electronegative atoms.
3.) Yes because hydrogen can easily form bonds with atoms that have a neutral charge.
4.) Yes because hydrogen can form these bonds with weakly electronegative atoms.
The correct statement for the given problem is
Further Explanation:
Intermolecular forces:
The forces that exist between the molecules are known as intermolecular forces (IMF). IMF includes both attractive as well as repulsive forces. They are electrostatic in nature and determine the bulk properties of the substances like melting and boiling points. Molecules are held in any substance due to these forces.
The various types of intermolecular forces are as follows:
1. Hydrogen bonding:
It is an attractive force that exists between hydrogen and more electronegative elements like N, O, F. It can either be intermolecular or intramolecular. Intermolecular hydrogen bonding is the one that occurs between different molecules. For example, the bond between HF and is an intermolecular hydrogen bond. Intramolecular hydrogen bonding occurs between various parts of the same molecule. Ortho-nitro phenol and salicylaldehyde show this type of bonding.
2. Ion-dipole forces:
It is an attractive force that occurs between an ion and a molecule consisting of a dipole. The force between and water molecule is an example of this force.
3. Ion-induced dipole forces:
It is an attractive force that occurs between an ion and a nonpolar molecule. It induces a dipole in the molecule, resulting in ion-induced dipole force. The bond between and oxygen molecule is an example of such kind of bond.
4. Dispersion forces:
Also known as London dispersion forces, van der Waals forces, instantaneous dipole-induced dipole forces. These forces exist between atoms and molecules. The forces that occur in molecule is a dispersion force.
(1) Hydrogen bond is the one formed between the highly electronegative atom and hydrogen. Although oxygen is a highly electronegative element, it also forms hydrogen bonds with hydrogen. But it there are also more electronegative elements, other than O that can form hydrogen bonds with hydrogen. So this statement (1) is incorrect.
(2) As is clear from the definition of hydrogen bonds, it is formed between highly electronegative elements (like F, O, and N) and hydrogen. So this statement (2) is correct.
(3) Hydrogen bonding is formed as the result of interaction between and an element that can induce a dipole in hydrogen. But neutral atom cannot induce any charge on hydrogen atom. So this statement (3) is incorrect.
(4) Hydrogen can form bonds with high electronegative elements and not with the weak electronegative elements. So the given statement (4) is incorrect.

No, hydrogen can only form these bonds with highly electronegative atoms. Therefore, the correct option is option 2.
When an electronegative atom is attracted to another electronegative atom nearby, a hydrogen atom that is covalently bound to a highly electronegative atom forms a hydrogen bond. This attraction results from variations in electronegativity values, which unbalances the distribution of electrons. While the electronegative atom acquires a partial negative charge, the electron-deficient hydrogen becomes weakly positively charged. The electromagnetic attraction between these partially positive and partially negative ions is known as a hydrogen bond, and it is quite powerful.
Therefore, the correct option is option 2.
