A brick of salt has a volume of 50cm³ and a mass of 100 grams what is the density
To find the density of a substance, you need to divide its mass by its volume. In this case, the mass of the brick of salt is 100 grams and the volume is 50 cm³.
Density (D) = Mass (m) / Volume (V)
Plugging in the values:
D = 100 g / 50 cm³
The density of the brick of salt is 2 g/cm³.
To find the density of a substance, you need to divide its mass by its volume. In this case, the mass is given as 100 grams, and the volume is given as 50 cm³.
Density = Mass / Volume
So, the density of the salt can be calculated as:
Density = 100 g / 50 cm³
Now, in order to get the density in proper units, we need to ensure that both mass and volume are in the same units. We can convert grams to kilograms (since density is often expressed in kg/m³) by dividing the mass by 1000:
Density = (100 g / 1000) kg / 50 cm³
Now, we also need to make sure that the units for volume are consistent. Since the question provided the volume in cm³, we need to convert it to m³ by dividing by 1,000,000 (since there are 1,000,000 cm³ in 1 m³):
Density = (100 g / 1000 kg) / (50 cm³ / 1,000,000 cm³)
Simplifying the equation further:
Density = 0.1 kg / (0.00005 m³)
Density = 2000 kg/m³
So, the density of the salt is 2000 kg/m³.
density = mass/volume
so plug in your numbers for g/cm^3
