1. A volume of 120.0 liters of a gas is prepared at a pressure of 400.0 mm Hg and a temperature 100.0 °C. The gas is placed into a tank under high pressure. When the tank cools to 10.0°C,
the pressure of the gas is 20.0 mm Hg. What is the volume of the gas?

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the final volume by using the combined ideal gas:

In such a way, by solving for the final volume, V2, we obtain:

Now, by plugging in the pressures, temperatures in Kelvins and initial volume, we will obtain:

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

the answer is 75.0%.
