hello! do you have an attempt you can share with us please?
Consider 100g of solution, 98g is acid
1) find vol of solution (100/1.8)ml
2) find moles of h2so4
=98/98(molar mass of h2so4 is 98g)
3) find molarity M1
4) use M1V1=M2V2
V1 is unknown and is what is asked
like the one i tried doing?
okayy thanls
Yes
oh i erased it cuz i was doing it in a rough work page
but i tried to find the the mass from the density
and tried to find the moles
Did you try this?
and then i got confued
💔
ill
try
that one
wait
can i get the link ???

You can check out my video that explain how you do these kind of questions in some detail.

You can do this from units and dimensions. The main thing you need to know is density is grams of solute, sorry, grams of solution divided by volume of solution in ml. Similarly, molarity is mold of solute divided by volume of solution in liters. So you see that there's something common in both of these denominators. But I need to convert, I need to find out how much volume is required. That's why your friend here has taken the basis to be 100 grams of solution. So you have 98 grams of H2SO4 in 100 grams of solution. So from there, you go say, OK, now with all the units, what can I do? You can play it by the ear. You don't have to mug any formulae. That requires a bit of practice.
