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
The density is 15 g/mL
Density = about 1.66 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.
Mass = 15 gm Volume = 2 cubic cm Density = Mass/Volume = 15/2 = 7 and 1/2 or 7.5 g per cm3
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.
