5. An object has a mass of 500 g and a volume of 600 cm³. The density of water is 1 g/cm³. Will this object float in water, and why?
- A. No, because its mass is greater than water
- B. Yes, because its volume is greater than water
- C. Yes, because its density is less than water's density
- D. No, because its volume is greater than its mass
