Answer
Solid A - cylinder c
Solid B - cylinder b
Solid C - cylinder a
Work Step by Step
So we have 3 solids:
Solid A
Solid B
Solid C
Now, we're going to calculate the volume of water so that these solids are able to displace.
1) Solid A
$Vol = 25g \times \frac{cm^{3}}{2.9 g} \times \frac{1 mL}{1 cm^{3}} = 8. 6 mL $
Solid A is therefore in cylinder (c).
2) Solid B
$Vol = 25g \times \frac{cm^{3}}{8.3 g} \times \frac{1 mL}{1 cm^{3}} = 3.0 mL $
Solid B is therefore in cylinder (b).
3) Solid C
$Vol = 25g \times \frac{cm^{3}}{3.3 g} \times \frac{1 mL}{1 cm^{3}} = 7. 6 mL $
Solid C is therefore in cylinder (a).
