A given mass of a gas occupies `143 cm^3` at `27^@C` and `700 mm Hg` pressure. What will be its volume at 300 K and 280 mm Hg pressure?

Explanation

To solve the problem, we will use the combined gas law, which states that for a given mass of gas, the ratio of the product of pressure and volume to temperature is constant. The formula is:

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