Here are the essential concepts you must grasp in order to answer the question correctly.
Density
Density is defined as mass per unit volume and is a crucial property of materials. It is typically expressed in kilograms per cubic meter (kg/m³). Understanding density allows us to compare the mass of different substances given their volumes, which is essential for solving the problem of finding the equivalent volume of water for a specific mass of ethyl alcohol.

Specific Gravity
Specific gravity is the ratio of the density of a substance to the density of a reference substance, usually water. It is a dimensionless quantity that helps in comparing the densities of different materials. For example, if ethyl alcohol has a specific gravity less than 1, it will float on water, and knowing this helps in determining how much water corresponds to the same mass as a given volume of ethyl alcohol.

Volume-Mass Relationship
The volume-mass relationship is a fundamental concept in physics that describes how the mass of a substance can be calculated from its volume and density. This relationship is expressed mathematically as mass = density × volume. In this problem, we need to use the density of ethyl alcohol to find its mass and then use the density of water to find the corresponding volume that has the same mass.
