You need to know the volume because the density is the ratio mass/volume.
To calculate the density of an object, you can use the formula: density = mass/volume. Given that the mass is 78 g and the volume is 15 cm³, the density would be 78 g / 15 cm³ = 5.2 g/cm³. Therefore, the density of the object is 5.2 g/cm³.
Density of that object is 2.8
You need a unit for the mass, not just a number. In any case, the idea is to divide the mass by the volume.
Density is the quotient of the mass and the volume. 15 grams ÷ 5.0 mL = 3.0 g/mL
Density = Mass/Volume = 15/60 = 0.25 grams per millilitre.
15 3x5=15
Density = about 1.66 g/mL
The density is 15 g/mL

You can find the mass of an object by multiplying its volume by its density. The formula to calculate mass is: mass = volume x density. Simply plug in the given values for volume and density to calculate the mass of the object.
The density of an object is determined by dividing its mass by its volume. This is expressed by the equation: Density = Mass/Volume. densitY is a measure of how much mass is contained in a given volume of the object.
Mass = 15 gm Volume = 2 cubic cm Density = Mass/Volume = 15/2 = 7 and 1/2 or 7.5 g per cm3
