now we are going to do another numerical
which is based on Faraday's first  law so
let us see what are the requirements
so as mentioned in the above question that
in electrolysis of AGNO3  0.7
gram of Ag is deposited
after a certain time so calculate the
quantity of electricity required in
Coulomb if the molar mass of Ag is given
as 107.9 so in this case let me tell you
which kind of data and what data are
been provided to us in this thing only
the weight is being provided and the
molecular weight is be provided and from
that thing we have to calculate what
would be the current in Kulik or what
would be the quantity of electricity
required in the Coulomb so let me tell
you Coulomb is the quantity that will
get only if the charge is for pulley if
when current is multiplied by the time
that means we have to calculate what
would be the value of I into T because
that has unit of ampere and type has
root of second so campaign in second is
nothing but the Coulomb so therefore we
have to calculate I into T but for that
we should know what would be the value
of zero zero so in this case the value
of Z will be one because AG has been
involved so let us see and let us
discuss in a very detailed way and let
us see how can we elaborate and how can
we estimate what will be the given
requirement or what will be the last
requirement so in this thing what they
have provided assist W that is weight
that is given as zero point seven gram
of Ag the next is molecular weight is
also provided to us which is 107.9 gram
per mole and the menu upset that we have
to carry good because it is a solution
of H 0 3 so AJ and O 3 gets dissociated
in the form of AG plus plus no.3 - so
the valency of AG in this
is one therefore said that is equivalent
weight is nothing but weight divided by
that is a monitor weight divided by wins
so the monitor wait is provided to us as
107.9 and that of balance e is 1 so that
for said that is equivalent weight for
silver in this case will be 107.9 and
from this all data we have to calculate
what would be the electricity or what
would be the value of i intruding so
therefore since we know the formula that
is w source to z into I into T divided
by 9 6 5 0 0 therefore the W that is
been provided to us in 0.7 and the value
of Z that is 107.9 and Q this Q is
nothing but I to D here by 9 6 5 0 0
therefore Q is goes to zero point 7 into
nine six five zero zero divided by 107.9
so let us see what is the answer that we
will get
so this is what we have got the answer s
six hundred and twenty six point zero
four Coulomb of charge that we have got
so it was the most easiest one and so
thank you friends for watching this
video and I hope you have got an idea
