Answer:
Concentration of the chemist's copper(II) sulfate solution is 0.43 mol/L
<em>Note: The volume of the flask is assumed to be 250 mL</em>
Explanation:
Since the volume of the volumetric flask is not given, we assume the volume its volume to be 250 mL.
Mass of copper (ii) sulfate = 17.2 g; molar mass of copper (ii) sulfate = 160 g/mol
Concentration in mol/L = number of moles/volume in litres
Number of moles of copper (ii) sulfate = 17.2 g / 160 g/mol = 0.1075 moles
Volume of flask in litres = 250 mL/1000 mL * 1 L = 0.250 L
Concentration = 0.1075 moles / 0.250 L = 0.43 mol/L
Therefore, concentration of the chemist's copper(II) sulfate solution is 0.43 mol/L
The group of atoms that is responsible for the characteristic properties of a family of organic compounds is called a <u>functional</u> group.
Functional groups are groups of one or extra atoms with exclusive chemical homes regardless of what's connected to them. The atoms of practical agencies are certain via covalent bonds with one another and with the relaxation of the molecule.
Functional groups include:
- hydroxyl,
- methyl,
- carbonyl,
- carboxyl,
- amino, phosphate,
- sulfhydryl.
An atom or institution of atoms that replaces hydrogen in a natural compound that defines the shape of a family of compounds and determines the properties of the family.
