Draw a freebody diagram, it will explain it really well
the boat is floating on top of the water, which means that the net acceleration in the y direction must be zero
the boat is not sinking (dominant downwards acceleration/force)
the boat is not flying (dominant upward acceleration/force)
that measn
now, if you drew the FBD, you only have 2 forces acting on the boat.
the upward bouyancy force on the boat and the downward force due to weight
since the net force is equal to zero
and thus

Answer:
"12.4 g/mL" would be the right solution.
Explanation:
The given values are:
Mass of the object,
= 149.8 g
Volume of the object,
= 12.1 mL
Now,
The Density will be:
⇒
On substituting the given values in the above formula, we get
⇒
⇒
