Answer:
The object will float on the surface of water if its density is less than the equal volume of water.
Explanation:
Density:
It is define as mass per unit volume.
d=m/v
it is mostly measure in g/mL
it is represented by ρ (rho)
The density of water is one gram per cubic centimeter. If the object is less denser than water it will float. If the density of object is greater than the density of water it will sink.
Other examples:
some rocks are more denser then water so they will sink in it.
density of oil is less than vinegar, so it will float on the surface of vinegar
Yes because it helps determine the properties the molecule has.

Explanation:
. A chemist investigates the boiling point, melting point, and flammability
of a compound called acetone, a component of nail polish remover.
Which of these properties are physical properties and which are
chemical properties?
Physical ( boiling point and melting point ).
Chemical ( flammability )
Answer:
930 g
Explanation:
D = m/V Multiply both sides by V
m = VD
<em>Data:
</em>
V = 372 cm³
D = 2.70 g/cm³
<em>Calculation:
</em>
m = 372 × 2.50
m = 930 g
The mass of Al is 930 g.
