48L of hydrogen gas is heated from -20c to 90c and the pressure is decreased from 760 mmHg to 740 month. What Is the final volume?

Answer:

To solve this problem, we can use the combined gas law, which states that (P1 * V1) / T1 = (P2 * V2) / T2, where P is pressure, V is volume, and T is temperature in kelvins.

First, we need to convert the temperatures from Celsius to kelvins by adding 273.15. So -20°C is equivalent to 253.15 K and 90°C is equivalent to 363.15 K.

Plugging in the known values into the combined gas law formula, we get:

(760 * 48) / 253.15 = (740 * V2) / 363.15

Solving for V2, we find that the final volume of the hydrogen gas is approximately 53.7 L.
