a sample of an unknow metal exists as a perfect cube that meausres 0/78 in on a side and weighs 61.4 grams. what would be the mass, in grams, of a diff sample of this metal that has a volume of 25.0 cm^3

  • Chemistry -

    Did you make a typo on 0/78 inches?

  • Chemistry -

    yes. i meant 0.78 sorry.

  • Chemistry -

    Convert 0.78 inches to ?cm. Then
    volume of the cube = (?cm)^3.
    density = mass/volume. You have mass and volume, solve for density.

    Then mass = volume x density.
    volume 25.0 cc.
    density from above.
