Which of the following `is//are` correct?
`100 mL` of `3.0 M HClO_(3)` reacts with excess of `Ba(OH)_(2)` according to the equation:
`Ba(OH)_(2) + 2 HClO_(3) rarr Ba (ClO_(3)) + 2H_(2) O`
`(Mw` of `Ba(ClO_(3))_(2) = 304 g mol^(-1))`

Options

A. 0.15 mol of `Ba(ClO_(3))_(2)` is formed
B. 3 mol of `Ba(ClO_(3))_(2)` is formed
C. `45.6 g` of `Ba(ClO_(3))_(2)` is obtained
D. `4.56 g` of `Ba(ClO_(3))_(2)` is obtained.

Answer

A, C

Explanation

a. mmoles of `HClO_(3) = 100 xx 3 = 300 "mmol"`
`= (300)/(1) "mmol of" Ba(ClO_(3))_(2)`
`= 150 "mmol" = 1.5 "mol"`
Wrong.
Weight of `Ba(ClO_(3))_(2) = 150 xx 10^(-3) xx 304 = 45.6 g`
Wrong.
