They're totally unrelated. No matter how low or high the molecular weight, you can always use more or less of it.

What is the molarity of 60.0 grams of NaOH dissolved in 750 milliliters of water?

Bumek [7]

Answer:

The correct answer option is B) 2.0 M.

Explanation:

We are given the number of grams of NaOH (Sodium Chloride) which are dissolved in 750 milliliters of water and we are to find its molarity.

We know the formula of molarity:

Molarity = (mass * 1000) / (volume * molecular mass)

Volume = 750 ml = 750 cm $^3$

Molecular mass = 40

Mass = 60 grams

Substituting these values in the above formula:

Molarity = $\frac{(60*1000)}{750*40}$ = 2.0 M

Aryan want to deposit silver on an iron spoon using silver nitrate as electrolyte. Which terminal of the battery he should conne

34kurt

Silver from the anode gets dissolved to reach the cathode, where the spoon will be plated.

<h3>What is electroplating?</h3>

Electroplating is a way of electrolysis, where a thin layer of metal is used to plate a determined object. It is a kinda process to purify a material you want.

The anode contains the metal you want to plate with, in this case, the Ag.

The anode contains the half-reaction of oxidation so:

Ag(s) → Ag ⁺ (aq) + e⁻

In the cathode, you have the spoon, which it takes place the half-reaction of reduction:

Ag ⁺ (aq) + e⁻ → Ag(s)

The electrolytic cell, where the redox reaction takes place, must be filled with a AgNO₃ solution.

Silver from the anode gets dissolved to reach the cathode, where the spoon will be plated.
