figure the moles of Ba(OH)2 (note formula) in 23.7grams
molesBa(OH)2= 23.7/formulamassBa(OH)2
I get about 0.14 moles
then consider the balanced equation:
Ba(OH)2 + H2SO4 >>> 2H2O + BaSO4
so you need the same amount of moles of sulfuric acid.
Molarityacid=molesacid/volumeinLiters
volumeacid=.14about/4=.045liters= about 45 ml
Your formula writing has to improve very quickly if you do not want to flunk. In chemsitry, there are great differences between capital letters and small letters.
