Question

According to the following reaction, how many moles of barium chloride will be formed upon the complete reaction of 0.307 moles hydrochloric acid with excess barium hydroxide?

hydrochloric acid (aq) + barium hydroxide (aq) barium chloride (aq) + water (l)

Answer 1

Answer:

0.1535mol

Explanation:

the balanced equation is

2HCL + Ba(OH)2 — BaCL2 + 2H2O

from the equation 2moles of hydrochloric acid reacts to give 1mole of barium chloride

i.e

2mol HCL — 1mol BaCL

0.307 mol HCL — 1 ×0.307/2 = 0.1535mol of Bacl
