how many moles of 18L of NH3 at 30 celcius and 912 mmHg? how many grams?

  • Dejanras: Answer is: mass of ammonia is 14.76 grams and amount is 0.87 moles.
    V(NH
    ) = 18 L.
    T = 30°C = 303.15 K.
    p = 912 mmHg ÷ 760 mmHg/atm= 1.2 atm.
    R = 0.08206 L·atm/mol·K.
    Ideal gas law: p·V = n·R·T.
    n
     = p·V / R·T.
    n(NH₃) = 1.2 atm ·18 L / 0.08206 L·atm/mol·K · 303.15 K.
    n(NH₃) = 0.87 mol.
    m(NH₃) = n(NH₃) · M(NH₃).
    m(NH₃) = 0.87 mol · 17 g/mol.
    m(NH₃) = 14.76 g.
