Final answer:
An object with a mass of 35.2 grammes and a volume of 98.2 mL has a density of 0.358 g/mL, which is less than water's density of 1.00 g/mL, indicating the object would float in water.
Step-by-step explanation:
To determine what an object with a mass of 35.2 grammes and a volume of 98.2 mL would do in water, we need to calculate its density. Density is mass divided by volume. Thus, the density of the object is 35.2 g / 98.2 mL = 0.358 g/mL. Since the density of water is 1.00 g/mL, any object with a density less than that of water will float, and if it has a higher density, it will sink. Therefore, because the density of the object is less than that of water, it would float.
