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
Answers
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
