Final answer:
To calculate the percent compensation by mass of hydrogen in NH₄HCO₃, determine the molar mass of NH₄HCO₃ and the mass of hydrogen in it. Calculate the molar mass of NH₄HCO₃ by adding up the molar masses of its constituent elements. Then, calculate the mass of hydrogen by multiplying the number of moles of hydrogen in NH₄HCO₃ by the molar mass of hydrogen. Finally, divide the mass of hydrogen by the molar mass of NH₄HCO₃ and multiply by 100 to get the percent compensation by mass of hydrogen.
Step-by-step explanation:
To calculate the percent compensation by mass of hydrogen in NH₄HCO₃, we need to determine the molar mass of NH₄HCO₃ and the mass of hydrogen in it. The molar mass of NH₄HCO₃ can be calculated by adding up the molar masses of all its constituent elements, which are: nitrogen (N) with a molar mass of 14.01 g/mol, hydrogen (H) with a molar mass of 1.008 g/mol, carbon (C) with a molar mass of 12.01 g/mol, and oxygen (O) with a molar mass of 16.00 g/mol.
So, the molar mass of NH₄HCO₃ = (4 x molar mass of H) + molar mass of N + molar mass of C + (3 x molar mass of O).
Once we know the molar mass of NH₄HCO₃, we can calculate the percent compensation by mass of hydrogen by dividing the mass of hydrogen in the compound by the molar mass of the compound and multiplying by 100. The mass of hydrogen can be calculated by multiplying the number of moles of hydrogen in NH₄HCO₃ by the molar mass of hydrogen.
