I think so, <span> how much of all chemistry is to do with numbers? A lot! So being good at mathematics makes a huge aspect of chemistry so much easier but if you aren't mathematical then you can work at it and become reasonably proficient at it.</span>
According to Avogadro's number there are 62.53 atoms of chlorine in 1.1x 10
moles of Cl atoms.
<h3>What is Avogadro's number?</h3>
Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.
According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.
Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number or number of moles×Avogadro's number.
ON substitution in above formula number of atoms=1.1×10²¹×6.023×10²³=62.53 atoms
Thus, there are 62.53 chlorine atoms in 1.1x 10 moles of Cl atoms.

Intermolecular bonding:
Water is a polar molecule exhibit dispersion forces and hydrogen bonding
Salt is a polar molecule exhibit dispersion forces and dipole dipole bonding
Same bonding capacity therefore similar bonding capacity, therefore salt able to dissolves in water
That's a lot of conversions...

<span>my answer is B.The electrical charge of the hydrogen atom is thought to be exactly zero. This is a consequence of the apparent equality of the magnitude of the electrical charges of the electron and the proton, and their opposite sign. The electrical charge of neutral atoms has been measured to be zero, with an uncertainty of something like 10^(-20) e, where e is the elementary charge.</span>
