What is the mass of an object with a density of 24 g/mL and a volume of 6 mL ?

  1. A.

    146 g

  2. B.

    142 g

  3. C.

    143 g

  4. D.

    144 g

Show answer & explanation

Correct answer: D

Density expresses how much mass is packed into a given volume of a substance. The relationship is Density = Mass ÷ Volume, which rearranges to give Mass = Density × Volume.

  1. The object's density is given as 24 g/mL and its volume is given as 6 mL.

  2. Substitute these values into the rearranged formula: Mass = 24 g/mL × 6 mL.

  3. Multiply 24 by 6 to obtain the mass: Mass = 144 g.

As a check, divide the computed mass by the given volume: 144 g ÷ 6 mL = 24 g/mL, which matches the density stated in the question, confirming the result.

Therefore, the mass of the object is 144 g.
