The formula if Idous Acid is HIO2
Answer:
1.12M
Explanation:
The initial concentration of the HCl solution is 3.99M. You are doing 2 dilutions:
In the first you take 326mL and dilute the solution to 976mL; that means you are diluting the solution:
976mL / 326mL = 2.99 times.
The concentration of this solution is:
3.99M / 2.99 = 1.33M
Now, in the second dilution, you take 100mL of the diluted solution and dilute it to 119mL. The concentration of this final solution is:
119mL / 100mL = 1.19 times.
1.33M / 1.19 =
<h3>1.12M</h3>

<span>Cu + 2 AgNO</span>₃<span> = 2 Ag + Cu(NO</span>₃<span>)</span>₂
mole ratio:
1 mole Cu --------------> 2 moles Ag
? mole Cu --------------> 3.50 moles Ag
moles Cu = 3.50 x 1 / 2
moles Cu = 3.50 / 2
= 1.75 moles
Answer B
hope this helps!
