Answer:
55.5atm
Explanation:
Using ideal gas law equation;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
Molar mass of BrCl = 79.9 + 35.5
= 115.4g/mol
* mole = 826.76 g ÷ 115.4g/mol
mole = 7.16mol
* Volume = 6342.7 mL = 6342.7/1000 = 6.3427L
* Pressure = ?
* Temperature = 325.77 °C = 325.77 + 273 = 598.77K
PV = nRT
P = nRT/V
P = (7.16 × 0.0821 × 598.77) ÷ (6.3427)
P = 351.98 ÷ 6.3427
P = 55.5atm
