Final answer:
The density of the substance is 1.908 g/cm³.
Step-by-step explanation:
The density of a substance can be calculated by dividing its mass by its volume. In this case, the mass is given as 248g and the volume is given as 130mL. To obtain the density, we will convert the volume to cubic centimeters (cm³) to match the units commonly used for densities of solids and liquids. Since 1mL is equal to 1cm³, the volume in cm³ is also 130.
The formula for density is: Density = Mass/Volume.
Substituting the given values, we have:
Density = 248g / 130cm³ = 1.908 g/cm³.
