At 650 mm hg a gas has a volume of 190 l what is its volume at standard pressure

Volume occupied by the gas at standard pressure is 162.5 L.

Explanation:

Pressure of the gas when it occupies volume of 190 L = 650 mmHg

Volume occupied by the gas when the gas is at standard pressure.

The value of standard pressure = 1 atm = 760 mmHg

According to Boyle's Law: (at constant temperature)

Volume occupied by the gas at standard pressure is 162.5 L.

hope that

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
