What is the mass of an object with a density of 24 g/mL and a volume of 6 mL ?
- A.
146 g
- B.
142 g
- C.
143 g
- 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.
The object's density is given as 24 g/mL and its volume is given as 6 mL.
Substitute these values into the rearranged formula: Mass = 24 g/mL × 6 mL.
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.
