What is the density of g/cm^3, of a piece of metal that has a mass of. 500kg and a volume of 63cm^3
What is the volume of a piece of iron (d=7.9 g/cm^3) that has a mass of. 50kg
Why did the metal go to the gym? Because it wanted to bulk up its density! Now, let's calculate it.
Density is mass divided by volume, so we'll divide the mass (500 kg) by the volume (63 cm^3):
Density = Mass / Volume
Density = 500 kg / 63 cm^3
So, the density of the metal is approximately 7.936 g/cm^3. Now that's one dense (but strong) piece of metal!
To find the density of a material, you need to divide the mass of the material by its volume.
In this case, you have the mass of the metal, which is 500 kg, and the volume, which is 63 cm^3.
To find the density, follow these steps:
1. Make sure the units for mass and volume are consistent. In this case, the mass is given in kilograms (kg) and the volume is given in cubic centimeters (cm^3). You need to convert the mass to grams (g) so that the units for mass and volume match. Since 1 kg is equal to 1000 g, the mass can be converted to 500,000 g.
2. Divide the mass (in grams) by the volume (in cubic centimeters). In this case, the mass is 500,000 g and the volume is 63 cm^3. Therefore, the density can be calculated as:
Density = mass / volume
Density = 500,000 g / 63 cm^3
3. Calculate the density. Dividing 500,000 g by 63 cm^3 gives you a density of approximately 7936.51 g/cm^3.
So, the density of the piece of metal is approximately 7936.51 g/cm^3.
look at the units
g/cm^3 * cm^3 = g
That is,
density * volume = mass
So plug in your numbers.
