Question

The density of water is 1 gm/ml. An object has a mass of 58 grams. What volume must it have in order to float in water?

Answer 1

Answer:

58mL

Explanation:

Given parameters:

Density of water  = 1g/mL

Mass of object  = 58g

Unknown:

The volume the object must have to be able to float in water = ?

Solution:

To solve this problem, we know that the object must have density value equal to that of water or less than that of water to be able to float.

We then set its density to that of water;  

   Density  = $\frac{mass}{volume}$  

      Volume  = $\frac{mass}{density}$  

So;

      Volume  = $\frac{58}{1}$   = 58mL
