The solubility of nitrogen gas in water at 25 °c and a nitrogen pressure of 1.0 atm is 6.9 × 10-4 m. the solubility of nitrogen in water at a nitrogen pressure of 4.5 atm is m.

Solubility of nitrogen in water at a nitrogen pressure of 4.5 atm is

Explanation:

According to Henry's law for solubility of a gas dissolved in a solvent-

where and are solubility of the gas at a pressure of and respectively.

Here, , and

So,

or,

or,

So, solubility of nitrogen in water at a nitrogen pressure of 4.5 atm is

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
