What is the density of a solid 1.5 kg paperweight that gets submerged in water and displaces 150 cm3 of water
150 cm^3 is the volume of the paperweight, since it will not float. Divide the mass (1500 g) by that number to get the density.
To find the density of the solid paperweight, we can use the formula:
Density = Mass / Volume
Given that the mass of the paperweight is 1.5 kg and it displaces 150 cm3 of water, we can substitute those values into the formula:
Density = 1.5 kg / 150 cm3
However, we need to ensure that the units are consistent. Grams (g) are commonly used for mass and cubic centimeters (cm3) for volume. Thus, we need to convert the mass from kilograms to grams:
1 kg = 1000 g
Therefore, the mass in grams would be:
1.5 kg * 1000 g/kg = 1500 g
Now we can calculate the density:
Density = 1500 g / 150 cm3
Simplifying this equation, the density of the paperweight is:
Density = 10 g/cm3
