Respuesta :
At STP,
Temperature, T = 273 K
Pressure, P = 1 atm
Moles of oxygen, n = 2.60
Volume of oxygen = V
As we know,
[tex]V = \frac{nRT}{P}[/tex]
[tex]V = \frac{2.60 X 0.0821 LX 273 K}{1 atm}[/tex]
[tex]V = 58.27 L[/tex].
Have you ever questioned the need for such sharp knives or the pointy ends on our nails? The idea of pressure has the answers to each of these queries. It is the ratio between the force being applied and the surface area being applied to. Pressure can be described as: the force applied perpendicularly to an object's surface divided by the surface area across which it is applied.
Since the pressure is a function of the area that the force is acting on, it can rise and fall without affecting the force. If the force applied remains constant, the pressure will rise as the surface gets smaller and vice versa.
