Interpretation: The balanced chemical equation and the element
Concept Introduction: The formula to calculate the number of moles is given as shown below:

Answer to Problem 59A
The element
Explanation of Solution
It is given that
The given value of mass of hydrogen gas is
Substitute the given values in the above formula to calculate number of moles of hydrogen.
The balanced chemical reaction shows that one mole of
Therefore, the molar mass of
The calculated molar mass is similar to the molar mass of
Thus, the element
