a sample of iron occupies a volume of 10.0cm3. if the density of iron is 7.9 g/cm3 what is the mass of the sample

Mass = volume x density

You have density and volume, substitute and solve for mass.

d=m/v

7.9g/cm³=x/10.0cm³
79 cm³
density=mass divided by volume.
divide your density by volume. if given mass divide mass and density. biggest number first.

To find the mass of the sample of iron, you can use the formula:

Mass = Density × Volume

Given:
Density of iron = 7.9 g/cm³
Volume of sample = 10.0 cm³

Substituting the values into the formula:

Mass = 7.9 g/cm³ × 10.0 cm³

Multiplying the numbers:

Mass = 79 g

Therefore, the mass of the sample of iron is 79 grams.

To find the mass of the sample, we can use the formula:

Mass = Density * Volume

Given that the volume is 10.0 cm^3 and the density of iron is 7.9 g/cm^3, we can substitute these values into the formula:

Mass = 7.9 g/cm^3 * 10.0 cm^3

Multiplying the values together, we get:

Mass = 79 g

Therefore, the mass of the sample of iron is 79 grams.
