The equivalent weight of an acid:

What is the mass of one molecule of the compound $C_{60}H_{122}$ in grams?

If the mass of an electron is halved,the mass of a proton is doubled,and the mass of a neutron is $3/4$ of its original mass,then what will be the new atomic mass of an $O^{16}$ atom?

Assuming chlorine element has two isotopes as $Cl^{35}$ and $Cl^{37}$ with their percentage abundance as $25\%$ and $75\%$ respectively. Find the average atomic weight.

The equivalent weight of an element is $4$. Its chloride has a $V.D$ of $59.25$. Then the valency of the element is:

If the equivalent mass of $S$ in $SO_2$ is $8$,what is the equivalent mass of $S$ in $SO_3$?
