37.5 mL of oxygen gas is collected at a pressure of 772 mm Hg. What is it’s volume at 716 mm Hg?

The volume of the gas at 716 mmHg comes out to be 40.43 mL. This problem is solved by using below equation.

 at constant temperature

Explanation:

Initial volume of gas = V = 37.5 mL

Initial pressure of gas = P = 772 mmHg

Final pressure of gas = P' = 716 mmHg

Assuming final volume of the gas to be V' mL.

   at constant temperature

Hence, volume of oxygen gas at 716 mmHg is 40.43 mL.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

i believe the answer is true.
