An object floats in a beaker as shown. when it was put into the beaker, it displaced an amount of water into the graduated cylinder at the left. given that the liquid in the beaker is water (density = 1 g/cm3), what is the mass of the object?

Respuesta :

Answer:

answer is  C. 10 g

Explanation:

: When an object floats, it displaces an amount of water that has the same mass as itself. Therefore, the mass of the water in the graduated cylinder is equal to the mass of the object. We can see that there are 10 mL of water in the graduated cylinder. We also know that the density of water is 1 g/mL. Since each mL of water has a mass of 1 g, then 10 mL of water has a mass of 10 g. If the mass of the displaced water is 10 g, then the mass of the floating object is also 10 g.
