I got 17.9grams for the first question and 0.3mol for the second.

All right. Let's wait for others to try it.
Meanwhile, I would like to see your working of the second question.

Q=It
15*1930=28950
I mole of chlorine is liberated by 96500C
xmole of chlorine is liberated by 28950.
Then make x the subject of the relation.

hehe. Here are the options: A 0.05. B 0.10. C 0.15 D 0.20

I will go with 'C' then. 2Cl-^ -->Cl2 +2e- Represents the discharge of chlorine

Have fun answering these

why did you get 0.3 initially? I got that too when I did it the first time.

No 2

I got 0.3 initially because I used Cl- instead of 2Cl-.

5) A quantity of electricity liberates 1.50g of aluminium from its ions. The mass of silver that will be liberated from its ions by the same quantity of electricity is
A. 10.80g. B 5.40g. C. 6.05g. D 3.03g. (Al = 27, Ag = 108)

6) what is the quantity of chlorine in moles liberated when a current of 15A is passed through molten potassium chloride in 1930 seconds? (IF = 96500C/mol)

5)for AL
3f------27g
x------1.5g
x=4.5f/27
for Ag
f----108g
4.5f/27---yg
y=4.5f*108/27f
y=45*108/10*27
y=9*54/27
y=54/3
y=18g

6)at the anode
Cl2 +2e -----2Cl-
therefore 1 mole of Cl2 is liberated by 2moles of electrons i.e 2f
2f-------1mole
15*1930=28950-----xmole
x=28950/2*96500
x=28950/19300=0.15mole

The possibility is high.... But it will b better if you are from the educationally less developed state so that with an agg of 68/69, will guarantee u of medicine. But if u r from the educationally developed state which isn't a catchment area of UNIBEN, then am afraid to tell u that score will not get u medicine but u will b given another course.

. no I'm not from eld state...

buh wah kinda course can I be given in place

I love this working of yours. By the way, did you try solving it directly without converting?
