Question

4. A metallic object of irregular shape displaces
21 mL of water when it is immersed in a
measuring cylinder containing water. If its
mass is 56.7 g, what is the density of the
metal?​

Answer 1

Answer:

Explanation:

Density = mass ÷ volume

Any object will displace its own volume of whatever fluid it is immersed in. So the question already tells you both the mass and the volume of the object. The rest is simple arithmetic.

Density = 56.7gm ÷ 21 ml = 2.7 gm/ml, which is also equal to 2.7kg/litre.
