oh okay cool , thanks ! :biggrin: um... could you teach me to calculate the final pH of a solution if 500mL of 10M H2SO4 is mixed with 2L of 3M HCL & 30L of de-ion water? I tried the titration method to find the molarity of de-ionized water( M1V1=M2V2) After that, i broke up HCL into...

Oh crap ! Sorry had a typo ! What i meant was mole of hydrogen would be 2 X the mole of the water molecules( H2O) i once did a question which i was asked to compare the mole of K+ between 2 different solutions of K+ions : Given that 2 solutions, 30mL of 0.15M K2CrO4, and 25mL of 0.08M...

Ok then,i'll get 24 apples A water molecule contains 2 hydrogen atoms,thus the mole of the water molecule would be 2 X the mole of the water molecule? but wait..isnt that the same as finding the mole of H+ ions in a water molecule?

hahaha ikr...um i think there are like 2 H in water so there are 1.204 X 10^24 atoms?

Hi guys ! I'm in serious need of help! Could you guys teach me how to attempt the following questions? I've tried everything..from reading up the notes(which has been trimmed along the years to make people pass)..to asking my teacher(He only explains briefly and in a way which i can't...
