How many moles in 5.125g of NaCl? In equation form! Plzzzz! HELP ME!

Chemistry
1 answer:
iVinArrow [24]3 years ago
5 0

Answer:

0.088mole

Explanation:

Given parameters:

Mass of the compound  = 5.125g

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we need first find the molar mass of the given compound.

Molar mass of NaCl  = 23 + 35.5 = 58.5g/mol

So;

 Number of moles  = \frac{mass}{molar mass}   = \frac{5.125}{58.5}    = 0.088mole

Look at the diagram of an electrolytic cell below.
Ipatiy [6.2K]

<em>The cathode is Y</em>

<h3><em>Further explanation</em></h3>

Electrolysis uses electrical energy to carry out redox reactions that are not spontaneous.

The ions in the solution flowing electrically will move towards to opposite charge of the electrode

The electrolysis material is an electrolyte which can be a solution or a melt.

In positive pole electrolysis cells - the anode is the site of the oxidation reaction, while the negative pole - the cathode is the reduction reaction site.

The result of the reaction in the anode is based on a substance that easily oxidized while the reaction in the cathode is based on a substance that easily reduced.

Electrons (electricity) enter an electrolysis cell through the negative pole (cathode)

The negative ion from the solution will move towards the positive electrode and release the electrons around the positive electrode (oxidation) and the electrons flow to the negative pole

Whereas around the negative electrode, there is electron binding and a reduction reaction occurs

So if we see the picture the cathode is Y
