What is the molarity Of a solution of nitric acid?

  • Answer:

    ok, so the reaction between these 2 is: Ba(OH)2 + 2HNO3 ----> Ba(NO3)2 + 2H2O you have 0.216 grams of barium hydroxide which is equal to approx 0.00126 moles (moles=mass/molar mass) therefore, u need 0.00126 X 2 moles of nitric acid as they react in a 1:2 molar ratio. thus u need 0.00252 moles HNO3.. volume of HNO3=20mL=0.02 L molarity=Moles/Volume=0.00252/0.02=0.1... mol/L have a good one. :)
