find the mass of h2 produced Binary compounds of alkali metals and hydrogen react with water to produce H2(g). The H2H2 from the reaction of a sample of NaH with an excess of water fills a volume of 0.505 L above the water. The temperature of the gas is 35 ∘C∘C and the total pressure is 755 mmHg

Mass of hydrogen produced is 0.0376 g.

Explanation:

The reaction equation will be as follows.

Now, formula for total pressure will be as follows.

Hence,    

                            = 755 mm Hg - 42.23 mm Hg

                            = 712.77 mm Hg

             = 0.937 atm

Now, we will calculate the moles of as follows.

      n = mol

         = 0.0187 mol

Therefore, mass of will be calculated as follows.

                   = 0.0376 g

Thus, we can conclude that mass of hydrogen produced is 0.0376 g.
