Answer:
HCl
Explanation:
Volume = 25L
Temperature = 25.0 oC + 273 = 298 K (Converting to kelvin units)
Pressure = 1.2 atm
Mass of gas = 44.7g
Formular of gas = HX
To solve this, we have to know the identity of X. One qay to do that is by obtaining the molecular mass of the compound.
To get the molar mass, we need the number of mole.
Using the ideal gas equation;
PV = nRT
where R = gas constant = 0.082 057 L atm K−1 mol−1
n = PV / RT
n = 1.2 * 25 / 0.082 057 * 298
n = 30 / 24.45
n = 1.227 mol
The relationship between number of moles and molar mass is given as;
Nummber f moles = mass / molar mass
Molar mass = mass / Number of moles
Molar mass = 44.7 / 1.227
Molar mass = 36.43 g/mol
Molar mass of gas X = Molar mass of H + Molar mass of X
36.43 = 1 + X
X = 36.43 - 1 = 35.43
Chlorine is the only element with molar mass approximate to 35.43
Hence X = Cl
The chemical formular = HCl
