N: 60 mol
p: 20 atm = 20×1013hPa = 20260 hPa
T: 50°C = 323 K
R: 83,14 hPa·dm³/mol·K
V: ?
.................
pV = nRT
V = nRT/p
V = (60×83,14×323)/20260
V = 79,529 dm³ ≈ 79,6 dm³
79,6 dm³ = 79,6 L

Answer:
I think it A not sure if I get it wrong sorry I need points.
It’s 1 or 3 sorry if this is wrong
I believe KI is not a a binary molecule.
