Answer:
A
Explanation:
The dissolving process depends on the interaction between solute and solvent (solvation) and the breaking up of the intermolecular bond between solutes. The former is exothermic in nature, while the later is endothermic. Energy is released when solute-solvent particles interact. When this energy exceeds the energy required to break intermolecular bonds between the solute particles, dissolution is exothermic.
16g.
mol=gram/molar mass
4.00mol=g/4.0 molar mass of Helium
4mol*4g/mol= 16grams
