Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Uhh is the answer 0.15M
how to do it but ?
Should I send ans or hints
hints
All of the H+ ions are coming from H2SO4
Really small hint but if you need more I can give
how can I find molarity of 4.9 gm h2S04 ? I was able to find no of moles
You find no moles by given mass / molecular mass
I did it
I am asking molarity
this one
Iska kyu nikalna hai molarity
huh ?
You have 2 terms of H2SO4
Phele no miles nikalo and liquid ka volume is given
Moles
mai bol rha hu pehle h2so4 ka to bas mass diya haina volume kaha hai ?
oh 250ml h20 is the volume ?
And 250ml from 0.1M H2SO4
Net volume is 500ml
accha
smjh gya
umm I am not getting the answers
Ans kya hai
0.15M is the correct ans
Should I write down and show ans ?
if you can then please
my brain is not braining
Galti se phele 0.01 likha tha question has 0.1
Also @iTeachChem sorry for ping but my issue with chem is jese in this question I knew how to do it and solve it but I just didn’t remember atomic no of sulphur (10th ke baad forgot pt after 10) I had to look at the PT
So how much should I remember
Have u tried the periodic table song? I listened to it and learnt it till zinc when I was in 3rd or something and till now use it when I forget an atomic number
But use it at ur own risk bc the only way I recall is using the song and not telling it properly lol, i can send link if u want
please share me also
Sure, dms
Do it
I’m pouring honey on you goat
lets close this one, shall we? @Abhi
total moles by total volume, as folks said :)
sure

hey the no of moles of H+ should be double that of H2SO4 ?, as it is H2
…………………………..
Conjugate base of H2SO4 is HSO4-
So no
accha
aesa hota hai thik he dhanyawaad

hey i dont think that matters here
if you put h2so4 in water, we assume it to be dibasic
yes
