A) 0.0050
B) 0.0030
C) 0.0015
D) 0.0075
Correct Answer: B
Solution :
\[Ba{{(OH)}_{2}}\xrightarrow{{}}B{{a}^{2+}}+2O{{H}^{-}}\] Thus 1 mole \[Ba{{(OH)}_{2}}\] gives 2 moles of hydroxide \[(O{{H}^{-}})\] ions. Hence, \[0.3\times 0.005\]moles of \[Ba{{(OH)}_{2}}\] will give \[=0.3\times 0.005\times 2\] = 0.0030 molesYou need to login to perform this action.
