Here are the essential concepts you must grasp in order to answer the question correctly.
Specific Gravity
Specific gravity is a dimensionless quantity that compares the density of a substance to the density of water at a specified temperature. It is calculated as the ratio of the density of the substance to the density of water (1 g/mL). A specific gravity less than 1 indicates that the substance is less dense than water, which is the case for the vegetable oil in this problem.

Density
Density is defined as mass per unit volume, typically expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³). It is a crucial property in determining how much mass is contained in a given volume of a substance. In this problem, knowing the specific gravity allows us to calculate the density of the vegetable oil, which is essential for finding its mass.

Mass Calculation
Mass can be calculated using the formula: mass = density × volume. In this context, once the density of the vegetable oil is determined from its specific gravity, we can multiply it by the volume (750 mL) to find the mass in grams. This relationship is fundamental in solving problems related to the properties of materials.
