Answer:
The number of moles of hydrochloric acid are 0.861
Explanation:
In first solution, the [HCl] is 11.7 M, which it means that 11.7 moles are present in 1 liter.
So we took 25 mL and we have to know how many moles, do we have now.
1000 mL ____ 11.7 moles
25 mL _____ (25 . 11.7)/1000 = 0.2925 moles
This are the moles, we add to the solution where the [HCl] is 3.25 M
In 1000 mL __ we have __ 3.25moles
175 mL ____ we have __ (175 . 3.25)/1000 = 0.56875 moles
Total moles: 0.2925 + 0.56875 = 0.861 moles
