The henry's law constant for n2 is 6. 2×10−4matm at 25∘c. what pressure of nitrogen is needed to maintain a n2 concentration of 0. 53 m?

Sagot :

The pressure of nitrogen which is needed to maintain a N2 concentration of 0. 53 m is 3.2 × 10^(4).

What is pressure?

It is defined as the continuous physical force applied on or against an object by something which is in contact with it.

It is also defined as the force per unit area.

What is henry's law?

The henry law constant is thr ratio of the partial pressure of compound in air to the concentration of compound in water at given temperature.

C= kp

where,

C is the concentration of compound = 0.53m

k is the henry constant = 6. 2×10−4matm

p is the pressure of compound

By substituting all the value we get,

C = 6. 2×10−4 × p

0.53 = 6. 2×10−4 × p

p = 0.53/6. 2×10−4

p = 3.2 × 10^(4)

Thus we find that the pressure needed to maintain a N2 concentration of 0. 53 m is 3.2 × 10^(4).
