Question

1. a plastic toy with a mass of 18 g occupies 9 cm3 of space. its density is○ 0.5 g/cm3○ 1.5 g/cm3○ 2.0 g/cm3○ 6. g/cm32. a graduated cylinder contains 30ml of water. you place an object inside and the water rises to 52 ml. what is the volume of the object?○ 22 cm3○ 30 cm3○ 52 cm3○ 82 cm33. a block has a mass of 23 grams and a volume of 10 cm3. using the table right, what material is the block made of?

Explanation:

Step1: Calculate density (1st question)

Density formula: $\text{Density} = \frac{\text{Mass}}{\text{Volume}}$
$\text{Density} = \frac{18\ \text{g}}{9\ \text{cm}^3} = 2.0\ \text{g/cm}^3$

Step2: Find object volume (2nd question)

Volume = Final water volume - Initial water volume
$\text{Volume} = 52\ \text{mL} - 30\ \text{mL} = 22\ \text{cm}^3$ (since $1\ \text{mL}=1\ \text{cm}^3$)

Step3: Note 3rd question limitation

The reference table for the 3rd question is missing, so it cannot be solved with the provided information.

Answer:

1. 2.0 g/cm3
2. 22 cm3
3. Cannot be solved: Required reference table is not provided.
