Answer:
Material is less dense than water so it will float in water.
Explanation:
Given data:
Mass of material = 110 g
Volume of material = 312 cm³
Will it float or sink in water = ?
Solution:
First of all we will calculate the density of material.
d = m/v
d = 110 g/ 312 cm³
d = 0.35 g/cm³
The density of water is 1 g/cm³ it means material is less dense than water so it will float in water.
