Answer:
110ml
Explanation:
<em>Using the dilution equation, C1V1 = C2V2</em>
<em>Where C1 is the initial concentration of solution</em>
<em>C2 is final concentration of solution</em>
<em>V1 is intital volume of solution</em>
<em>V2 is final volume of solution.</em>
From the question , C1=6M, C2=0.5M, V1=10ml, V2=?
volume of water added = final volume -initial volume
= 120-10
=110ml
Explanation:
It is known that in one day there are 24 hours. Hence, number of seconds in 24 hours are as follows.
Hence, total charge passed daily is calculated as follows.
And, number of Faraday of charge is as follows.
= 134300.52 F
The oxidation state of aluminium in is +3.
So, if we have to produce 1 mole of Al(s) we need 3 Faraday of charge.
Therefore, from 134300.52 F the moles of Al obtained with 89% efficiency is calculated as follows.
= 39842.487 mol
or, =
Molar mass of Al = 27 g/mol
Therefore, mass in gram will be calculated as follows.
Mass in grams =
=
= 1075.7 kg/day
Thus, we can conclude that the daily aluminum production of given aluminium is 1075.7 kg/day.
