Answer:
0.5875L
Explanation:
concentration = mole/ volume
n(LiCl) = 20 / (7 + 35.5) = 0.47 mol
volume = mole / conc.
volume = 0.47 /0.8
= 0.5875 dm³ = 0.5875L
Answer:
2HNO3 +Na2CO3 → CO2 + H2O + 2NaNO3
Initial volume of the balloon =
= 348 mL
Initial temperature of the balloon
= 
Final volume of the balloon
= 322 mL
Final temperature of the balloon = 
According to Charles law, volume of an ideal gas is directly proportional to the temperature at constant pressure.

On plugging in the values,
