The mass of Xe present in the syringe given the data is 0.183 g
How to determine the mole of Xe
- Volume (V) = 35 mL = 35 / 1000 = 0.035 L
- Pressure (P) = 0.980 atm
- Temperature (T) = 298 K
- Gas constant (R) = 0.0821 atm.L/Kmol
- Number of mole (n) =?
Using the ideal gas equation, we can obtain the mole of Xe as follow:
n = PV / RT
n = (0.98 × 0.035) / (0.0821 × 298)
n = 0.0014 mole
How to determine the mass of Xe
- Mole = 0.0014 mole
- Molar mass of Xe = 131 g/mole
- Mass of Xe = ?
Mass = mole × molar mass
Mass of Xe = 0.0014 × 131
Mass of Xe = 0.183 g
