Answer:
The answer is option A
Step-by-step explanation:
To find out if the object sink or float in water we must first find the density of the object
![density = (mass)/(volume) \\](https://img.qammunity.org/2021/formulas/chemistry/college/2qztd1zu9lpwav17leag2cjjn695yipoje.png)
From the question
mass of object = 2 g
volume = 4 mL
The density is
![density = (2)/(4) = (1)/(2)](https://img.qammunity.org/2021/formulas/chemistry/high-school/4vgm4u9jqx4vk33bdddakbmjtb79msabp7.png)
We have the answer as
0.5 g/mL
The object will float on water since it's density is less than that of water which is
1.0 g/mL
Hope this helps you
