Question

При взаимодействии 11,4л аммиака с соляной кислотой получили 20 г NH4CL вычислите массовую долю выхода продукта реакции. Пожалуйста!!!

Answer 1

Для начала мы вычилсим теоретический выход , из 11.4 литра аммиака, мы получили 27.22 грамм.
А по условии нам дали ,что мы получили 20 гр.
Найдем выход продукта , практический делим на теоретический , и умножим на 100%.

Answer 2

Calculation of the Mass Fraction of the Reaction Product

To calculate the mass fraction of the reaction product, we need to determine the amount of NH4Cl produced and compare it to the amount of NH3 initially reacted.

Given: - Volume of ammonia (NH3) reacted = 11.4 L - Mass of NH4Cl produced = 20 g

To calculate the mass fraction, we can use the following formula:

Mass Fraction = (Mass of NH4Cl produced / Total mass of reactants) x 100%

To find the total mass of reactants, we need to convert the volume of ammonia to mass using its molar mass and the ideal gas law.

1. Convert the volume of ammonia to moles: - The molar volume of an ideal gas at standard temperature and pressure (STP) is 22.4 L/mol. - Therefore, the number of moles of NH3 can be calculated as follows:

Number of moles of NH3 = (Volume of NH3 / Molar volume at STP)

Substituting the given values:

Number of moles of NH3 = (11.4 L / 22.4 L/mol)

2. Calculate the mass of NH3: - The molar mass of NH3 is 17.03 g/mol. - Therefore, the mass of NH3 can be calculated as follows:

Mass of NH3 = (Number of moles of NH3 x Molar mass of NH3)

Substituting the calculated value from step 1 and the molar mass of NH3:

Mass of NH3 = (Number of moles of NH3 x 17.03 g/mol)

3. Calculate the total mass of reactants: - The total mass of reactants is the sum of the mass of NH3 and the mass of HCl. - Since the amount of HCl is not provided, we cannot calculate the exact total mass of reactants. Therefore, we will assume that the reaction is stoichiometric, meaning that the amount of HCl is equal to the amount of NH3 reacted.

Total mass of reactants = Mass of NH3 + Mass of HCl

4. Calculate the mass fraction of NH4Cl: - Now we can calculate the mass fraction of NH4Cl using the formula mentioned earlier:

Mass Fraction = (Mass of NH4Cl produced / Total mass of reactants) x 100%

Substituting the given value for the mass of NH4Cl and the calculated value for the total mass of reactants:

Mass Fraction = (20 g / (Mass of NH3 + Mass of HCl)) x 100%

Please note that without the exact amount of HCl reacted, we cannot provide an accurate calculation of the mass fraction of the reaction product.
