Question

What is the volume of a given mass of hydrogen at a pressure of 2.50 bar, if its volume is 3.15L at 1.00bar

Answer 1

Answer:

The temperature remains constant.

We solve this problem using the Boyle’s Law

{ { P }_{ 1 }{ V }_{ 1 }={ P }_{ 2 }{ V }_{ 2 } }

Volume of oxygen is 3.15 L at 1.00 atm.

Let { V }_{ 2 }= 3.15 L and { P }_{ 2 }= 1

Find the volume of oxygen at 2.50 atm

Let { P }_{ 1 } =2.50

{ { P }_{ 1 }{ V }_{ 1 }={ P }_{ 2 }{ V }_{ 2 } }

{ { V }_{ 1 }= }\frac { { P }_{ 2 }{ V }_{ 2 } }{ { P }_{ 1 } }={ { V }_{ 1 }= }\frac { 3.15 }{ 2.5 } =1.26L

The volume of a sample of oxygen is 1.26 L.
