Answer:
2/15
Step-by-step explanation:
The answer choices to this question do not make sense since probability is a measure that is always <= 1.0
Based on the number of times a particular colored tile is drawn we can assume that at the minimum there are 6 green, 20 red, 7 blue, 8 purple and 4 black tiles
Total number of tiles = 6 + 20 + 7 + 8 + 4 = 45
Probability of drawing a green tile = 6/45 = 2/15
Density (D) is the quotient obtained when mass (m) is divided by volume (v).
D = m / v
The volume is the difference of the volume read after and before the object is placed in the beaker,
v = 23.1 mL - 18.5 mL = 4.6 mL
Substituting the known values for the density,
D = 8.24 g / 4.6 mL = 1.79 g/mL
Thus, the density is approximately equal to 1.79 g/mL.
