Answer:
The gas will occupy a volume of 1.702 liters.
Explanation:
Let suppose that the gas behaves ideally. The equation of state for ideal gas is:
(1)
Where:
- Pressure, measured in kilopascals.
- Volume, measured in liters.
- Molar quantity, measured in moles.
- Temperature, measured in Kelvin.
- Ideal gas constant, measured in kilopascal-liters per mole-Kelvin.
We can simplify the equation by constructing the following relationship:
(2)
Where:
,
- Initial and final pressure, measured in kilopascals.
,
- Initial and final volume, measured in liters.
,
- Initial and final temperature, measured in Kelvin.
If we know that ,
,
,
and
, the final volume of the gas is:
The gas will occupy a volume of 1.702 liters.
Explanation:
The given data is as follows.
= 10 mM =
M
= 750 ml,
= 5 ml
= ?
Therefore, calculate the molarity of given NaCl stock as follows.
= 1.5 M
Thus, we can conclude that molarity of given NaCl stock is 1.5 M.
