So... Ba(OH)2 can disassociate in water. we then can consider it through its molecular ratio. For each Ba2+ ion, there is 2 OH- ions. Since you have x amount of moles of Ba(OH)2, you have 2x moles of OH- ions. You then can do the same thing with the NaOH and add the OH- moles up. From there you divide by the volume of the BaOh and NaOH

second one gave u more info than needed to make it tricky. just find the moles of c6h12O6, then divide by the volume. THe concentration is maintained in a sample because we are considering molarity which is a unit/volume. hence, even if u had a 10ml volume extracted from the 200mls, the 10mls still has the same concentration.
Yeah... Thats what I was thinking as well. Its just I don't know what to do from there. I know the basic fundamentals, but I can't make any progress with it. Its really fustrating. 😭 . I hate Molarity and Molaity so much ( Anything to do with concentration, to be honest ).

it takes heaps of practice mate. It's good you're doing things now. I wish I did that when I was younger lmfao. Lowkey just grind this shit out instead of your yr 10 stuff if ur confortable w the content. Genuinely, the chemistry course for yr 10 is a joke. Basically the same shit/less than the yr 9 syllabus. You can use that time better.

for pdhpe how do you study?
i make sure that i actually know my syllabus like i can recite it and all the subheading of it
making written summaries on my own (idk it helps me more and i can remember better if i do it myself)
and i do a lot of practice questions under timed conditions and i give to my teacher to mark

rinse & repeat ;-)
