Answer:
4.55 * 10^23 molecules
Explanation:
This is a conversion problem. We know that one mole has 6.022 *10^23 particles or molecules so we can use this as a conversion factor.
0.755 mol ( 6.022*10^23 molecules/ 1 mol)
=4.55*10^23 molecules
Colligative properties depend on the amount of solute dissolved in a solvent. These set of properties do not depend on the type of species present. These properties include freezing point depression, boiling point elevation, osmotic pressure and vapor pressure lowering.
Although coal and diamonds are both composed of carbons alone, they differ in their properties because of the bonds present in each substance. Diamonds are composed of covalent bonds which are strong and is crystalline in nature which makes it sturdier. Coal is amorphous which allows the slipping of irregular layers to each other making coal brittle
