Answer:
<h3>The answer is 200 cm³</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 150 g
density = 0.75 g/cm³
We have
We have the final answer as
<h3>200 cm³</h3>
Hope this helps you
Compound is a group of same molecules, Element is a group of same atoms and mixture is combination of two or more pure substances.
What are Molecules ?
Molecules are the combination of two or more different atoms combine in a fixed ratio.
Molecules can be independently founded.
Atoms are always founded in combined state and does not occurs independently except rare earth elements which belongs to 18th group of periodic table.
Chemicals are taken in compound state But they undergo chemical reaction individually in molecular level.
Hence, Compound is a group of same molecules, Element is a group of same atoms and mixture is combination of two or more pure substances.

Answer:
The attractive forces must be overcome are :
Explanation:
For the compound to dissolve the attractive forces existing between atoms of the compound must be reduced
<u>CsI is ionic compound </u><em>and its molecules are held together by ionic(electrostatic) force . These force must be weakened for its dissolution</em>
Forces in HF <em>:</em>
<em>1 .Hydrogen Bonding : In HF strong intermolecular Hydrogen Bonding exist between the electronegative F and Hydrogen</em>
2. Dipole - dipole : <em>HF is polar . So it is a permanent dipole and has dipole diople interaction</em>
