NH3 molecular weight is 17.
So, 22.4 ltr = 17 gm
56 ltr = ?
(56×17)/22.4 = 42.5 gm.
So, 22.4 ltr = 17 gm
56 ltr = ?
(56×17)/22.4 = 42.5 gm.

PV = nRT.
R = 8.314 Pa*M^3/mol * K.
n = PV/RT = (101325 * (56/1000)) / (8.314*273.15)
n=2.498 mole.
=> n=mass/Mwt.
2.498 = mass/17,
=> mass = 42.47 gm.
R = 8.314 Pa*M^3/mol * K.
n = PV/RT = (101325 * (56/1000)) / (8.314*273.15)
n=2.498 mole.

2.498 = mass/17,
=> mass = 42.47 gm.

@Nader
At STP T = 0°C.
At NTP T = 20°C.
At SATP T = 25°C.
At STP T = 0°C.
At NTP T = 20°C.
At SATP T = 25°C.
