Initial concentration of magnesium nitrate M1 = 2.13 M
Initial volume of magnesium nitrate, MgNO3 V1 = 1.24 L
Final concentration of MgNO3, M2 = 1.60 M
Let the final volume of MgNO3 upon dilution be V2
Formula to use:
M1*V1 = M2*V2
V2 = M1*V1/M2
= 2.13 M * 1.24 L/1.60 M = 1.65 L
Thus, the final volume of magnesium nitrate solution upon dilution is 1.65 L
The relationship between the two is that the higher the molecular motion is, the higher the temperature is.
The equation that represents photosynthesis is ,

The correct option is (c).

What is photosynthesis?
•This is process performed by green plants to prepare its food using sunlight and carbon dioxide.
•Oxygen and Glucose are the products obtained after photosynthesis.
•This process takes place in chlorophyll of a cell(in chloroplasts)
•These are of two types , light dependent reactions and light independent reactions
•This is was first discovered by Jan Ingenhouse.
Answer:

Explanation:
The boiling point depends on the intermolecular forces between the molecules of the compound.
have dipole- dipole interactions because there is the difference in electronegativity values of the atoms in the molecules.
posses hydrogen bonding.
: The bond in the molecule is C-H, which is non-polar in nature because the carbon and the hydrogen having very similar electronegativity values.
The intermolecular force acting in the molecule are induced the dipole-dipole forces or London Dispersion forces / van der Waals forces which are the weakest intermolecular force.
Hence, it has the weakest bond, so it takes least amount of the energy and hence the lowest boiling point.
