Question

calculate the molarity of a BaOH2 solution if 1900 mL is completely titrated by 261 mL of 0.505 M HNO ---- PLEAS HELP

Answer 1

first of all write a balanced equation between BaOH2 and HNO3

Answer 2

then you have molarity and volume of HNO3
so find mole using molarity= mole/ volume
thus mole= molarity * volume

Answer 3

then after u find the mole, look at the ratio between Ba(OH)2 and HNO3 then according to that ratio u can find mole of Ba(OH)3
then use molarity= mole/ volume
since u'll find mole and u already have volume now u can find molarity of Ba(OH)2

Answer 4

if its not clear let me know i'll show with numbers, but i hope u get it :)

Answer 5

btw its HNO or HNO3?
well whatever that is u still do same working :)
