Answer:
Substance A
Explanation:
A substance that has a higher density than water will sink in water, while that with a lower density than water will float on water.
Substance A, with a lower density of 0.98 g/ml as compared to that of water (1.0 g/ml) will thus float in water.
What is density?
Density is defined as the amount of substance per unit volume. The concept of density is usually one of comparison, which means whether a substance with a particular density value will sink or float will depend on the fluid's density it is placed in.
A higher density means that the substance has a higher mass per unit volume, so it's "heavier" and will thus sink.
