The balanced chemical equation for the reaction of ammonia hydroxide (NH4OH) producing ammonia (NH3) is:
NH4OH → NH3 + H2O
The equation shows that 1 mole of NH4OH produces 1 mole of NH3.
To determine the number of moles of NH3 produced from 7.50 g of NH4OH, we need to first calculate the molar mass of NH4OH:
NH4OH = 1 x 14.01 (atomic mass of N) + 4 x 1.01 (atomic mass of H) + 1 x 16.00 (atomic mass of O) = 35.05 g/mol
Next, we can use the following formula to calculate the number of moles:
moles = mass / molar mass
moles of NH4OH = 7.50 g / 35.05 g/mol = 0.214 mol
Since 1 mole of NH4OH produces 1 mole of NH3, the number of moles of NH3 produced is also 0.214 mol.
Therefore, 7.50 g of NH4OH produces 0.214 moles of NH3.
