Answer:
0.0006 mole
Explanation:
Considering:
Or,
Given :
For HCl :
Molarity = 0.100 M
Volume = 6.0 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 6.0×10⁻³ L
Thus, moles of potassium iodide :
Moles of HCl = 0.0006 moles
From the reaction shown below:-
1 mole of HCl reacts with 1 mole of sodium carbonate.
So,
0.0006 mole of HCl reacts with 0.0006 mole of sodium carbonate.
<u>Moles of sodium carbonate = 0.0006 moles</u>
Answer:
V₂ = 317 L
Explanation:
Given data:
Initial number of moles of hydrogen = 18.9 mol
Initial volume of gas = 428 L
Final volume = ?
Final number of moles = 14.0 mol
Solution:
According to the Avogadro law,
Number of moles of gas is directly proportional to the volume of gas at constant temperature and pressure.
Mathematical expression:
V₁/n₁ = V₂/n₂
V₁ = Initial Volume of balloon
n₁ = initial number of moles
V₂ = Final volume of balloon
n₂ = Final number of moles
Now we will put the values.
428 L / 18.9 mol = V₂/ 14 mol
V₂ =428 L × 14 mol / 18.9 mol
V₂ = 5992 L /18.9
V₂ = 317 L
