The question is incomplete, the complete question is:
A chemist prepares a solution of vanadium (III) chloride (VCl3) by measuring out 0.40g of VCl3 into a 50.mL volumetric flask and filling to the mark with distilled water. Calculate the molarity of Cl− anions in the chemist's solution. Be sure your answer is rounded to the correct number of significant digits.
Answer:
0.153M of anions
Explanation:
First we calculate the concentration of the solution. From m/M= CV
m=given mass, M= molar mass, C =concentration of solution, V= volume of solution
Molar mass of compound= 51 + 3(35.5)= 157.5gmol-1
0.4g/157.5gmol-1= C×50/1000
C= 2.54×10-3/0.05= 0.051M
But 1 mole of VCl3 contains 3 moles of anions
Therefore, 0.051M will contain 3×0.051M of anions= 0.153M of anions

Answer: Option (b) is the correct answer.
Explanation:
A covalent bond is defined as the bond that is formed by sharing of electrons between the two chemically combining atoms.
For example, in a molecule.
As the valency of each carbon atom is 4, valency of each hydrogen atom is 1, and valency of each oxygen atom is 2.
So, in each one outermost electron of carbon atom is shared by each one outermost electron of hydrogen atom.
The fourth outermost electron is shared by one outermost electron of oxygen atom and the other outermost electron of oxygen atom is shared by the hydrogen atom of -OH.
Hence, we can conclude that there are total 5 covalent bonds present in the formation of methyl hydroxide ( or methanol).
