The 0.25 volume in liters of 1.0 M solution is required to provide 0.5 moles of
(aq).
Calculation,
The Potassium carbonate dissolves as follows:
→
The mole ratio is 1: 2
It means, the 1 mole required to form 2 mole of
(aq).
To provide 0.5 mole of (aq) = 1 mole ×0.5 mole /2 mole required by
.
To provide 0.5 mole of (aq) ,0.25 mole required by
.
The morality of = 1 M = number of moles / volume in lit
The morality of = 1 M = 0.25 mole/ volume in lit
Volume in lit = 0.25 mole / 1 M = 0.25 mole/mole/lit = 0.25 lit

Answer:
1.82 L
Explanation:
We are given the following information;
- Initial volume as 2.0 L
- Initial temperature as 60.0°C
- New volume as 30.0 °C
We are required to determine the new volume;
From Charles's law;
Where, are initial and new volume respectively, while
are initial and new temperatures respectively;
Rearranging the formula;
Therefore, the new volume that would be occupied by the gas is 1.82 L
