Question

a solid with mass of 19m39bis added to a graduated cylinder filled with water to the 25.0 ml mark.after the solid sinks to the bottom, the wqter level is at 35.8 ml.calculate the density of solid​

Answer 1

Answer:

This means that you can figure out the volume of the metal by looking at the volume occupied by the water + metal and at the volume occupied by the water alone in the cylinder.

More specifically, the volume of the metal will be

V

metal

=

V

water + metal

−

V

water

In your case, you will have

V

metal

=

15.5 mL

−

10.0 mL

=

5.0 mL

Now, the density of the metal tells you the mass of one unit of volume of this metal. Since you're working with milliliters, one unit of volume will be

1 mL

.

Your goal will thus be to figure out the mass of

1 mL

of this metal. You know that

5.0 mL

have a mass of

9.25 g

, so use this as a conversion factor to find

1.0

mL

⋅

9.25 g

5.0

mL

=

1.85 g

So, if

1 mL

has amass of

1.85 g

, it follows that the density of the metal will be 1.85gm^-1
