324g of 20% by mass of Ba(OH)2 solution

Asked by arunparewa2000 | 27 Oct, 2021, 06:59: PM
The mass of Ba(OH)2 is 342 g.
The molar mass of Ba(OH)2 is 171 gm
Hence, 1 mole of Ba(OH)2 is the molar mass of Ba(OH)2 is 171 gm
So, for 342 g. wil be x

We know 100% by mass is 2moles hence 20% will be x.


As given the molarity of HNO3 is 2M, So, the total moles=

Total acidic excess moles = 2.4 - 0.8 = 1.6
The total volume of Ba(OH)2 is 

The volume of HNO3 is 1200ml
Hence the total volume of Ba(OH)2 = 1200+600 =1800 ml
