To determine what will happen when an object with a mass of 354 g and a volume of 354 cm³ is placed in water, we can calculate its density.
Density is calculated using the formula:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
Given:
- Mass = 354 g
- Volume = 354 cm³
Calculating the density:
\[ \text{Density} = \frac{354 \text{ g}}{354 \text{ cm}^3} = 1 \text{ g/cm}^3 \]
The density of water is also approximately 1 g/cm³. When an object has a density equal to the density of the fluid it is placed in, it will neither sink nor float — it will remain suspended in the fluid.
Therefore, the correct response to what will happen when this object is placed in water is:
The object will hang suspended in the middle of the water.
