<h3>
<u>How to find?</u></h3>
For solving this question, We need to know how to find moles of solution or any substance if a certain weight is given.
<h3>
<u>Solution:</u></h3>
Atomic weight of elements:
Ca = 40
C = 12
O = 16
❍ Molecular weight of
= 40 + 12 + 3 × 16
= 52 + 48
= 100 g/mol
❍ Given weight: 10 g
Then, no. of moles,
⇛ No. of moles = 10 g / 100 g mol‐¹
⇛ No. of moles = 0.1 moles
☄ No. of moles of Calcium carbonate in that substance = <u>0.1 moles</u>
<u>━━━━━━━━━━━━━━━━━━━━</u>
The conductance of the electric current through the electrolytic solution increases with increase in concentration.
<h3>What is electrolysis?</h3>
The term electrolysis has to do with a situation in which liquids conduct electricity by the movement of ions.
The conductivity of the solution depends on the ions present in the solution. Thus, the conductance of the electric current through the electrolytic solution increases with increase in concentration.
