Answer:
3.05 g
Explanation:
The reaction that takes place is:
- 4HCl + O₂ → 2Cl₂ + 2H₂O
As the decomposition not necessarily was complete we'll work with the<em> given mass of product formed</em>. We convert <u>the 12 grams of chlorine to moles</u>, using its <em>molar mass</em>:
- 12 g ÷ 70.906 g/mol = 0.169 mol
Then we <u>convert Cl₂ moles to H₂O moles</u>:
- 0.169 mol Cl₂ *
= 0.169 mol H₂O
Finally we <u>convert moles to grams</u>:
- 0.169 mol H₂O * 18 g/mol = 3.05 g
Explanation:
When iodine heptafluoride reacts rapidly with water to give a mixture of periodic acid and hydrofluoric acid. Reaction equation for the same is as follows.
As it is given that there are moles of iodine heptafluoride are present. Molar mass of
is 259.9 g/mol. Molar mass of
is 227.94 g/mol and molar mass of HF is 20.01 g/mol.
Now, according to the reaction equation M
gives
M
.
Also, the volume is given as 795 ml or 0.795 L (as 1 mL = 0.001 L).
Hence, calculate the concentration of into the solution as follows.
Concentration =
=
= mol/L
or, = 0.047 M
Now, as 1 mol of produces 7 mol HF. So,
M HF.
Therefore, concentration of HF will be calculated as follows.
Concentration of HF =
= 0.33 M
Thus, we can conclude that concentration of periodic acid is 0.047 M and concentration of hydrofluoric acid is 0.33 M.
