Calculate the mass of nitrogen dissolved at room temperature in an 99.0 l home aquarium. assume a total pressure of 1.0 atm and a mole fraction for nitrogen of 0.78. express your answer using two significant figures.

Explanation:

The given data is as follows.

          = 1 atm,         = 0.78

Now, we will calculate the partial pressure of given nitrogen gas as follows.

                        =

                        = 0.78 atm

According to the Henry's law we will calculate the solubility of nitrogen as follow.

                       =

                       =

Now, for 99.0 L the amount of nitrogen gas dissolved is calculated as follows.

        =

        = 1.32 g

Thus, we can conclude that the mass of nitrogen dissolved at room temperature in an 99.0 L home aquarium is 1.32 g.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
