Answer:
The answer to your question is 0.3 moles of NaCl
Explanation:
Data
NaCl = ?
Al(NO₃)₃ = 0.1 moles
Balanced reaction
Al(NO₃)₃ + 3NaCl ⇒ 3NaNO₃ + AlCl₃
Now, use proportions to solve the problem
1 mol of Al(NO₃)₃ ------------ 3 moles of NaCl
0.1 moles of Al(NO₃)₃ -------- x
x = (0.1 x 3) / 1
x = 0.3 moles of NaCl
Sodium/natrium is a metal from first column group so it should have one 1+ charge. Phosphate ion has 3- charge. That is why there 3 natrium ion for 1 phosphate ion when this molecule is dissolved in water. The ion formula would be:
(Na)
(PO
) ==> 3 Na
+ PO

<span> I got (a). The answer was 7.53. But when I try to solve (d), I keep getting the wrong answer. I subtracted the moles of NaOH from the acid and added the moles to the base. Then I did Ka = (x*([NaClO]+x))/([HClO - x) and then I found the pH</span>
500 meters is the correct answer :)
