Final answer:
Nonpolar solvents, such as n-hexane and toluene, can dissolve nonpolar materials like grease and oil.
Step-by-step explanation:
The solvent that will dissolve nonpolar materials like grease and oil is a nonpolar solvent. Nonpolar solvents have similar intermolecular forces as nonpolar substances, allowing them to dissolve nonpolar solutes. Examples of nonpolar solvents include n-hexane and toluene.
