Certain amount of a gas at `25^@C` and 76cm Hg occupies volume of 12.0L. What will be the pressure at a height where temperature is `10^@C` and volume is 12.8L?

Explanation

To solve the problem, we will use the Ideal Gas Law, which states that for a given amount of gas, the relationship between pressure (P), volume (V), and temperature (T) can be expressed as:

\[ PV = nRT \]

Since the number of moles (n) and the gas constant (R) are constant for the same gas, we can use the following relationship for two different states of the gas:

\[
\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}
