almost positive that its synthesis
Answer:
7.055 atm
Explanation:
T = (273 + 37)K = <em>310K</em>
The ideal gas constant =<em> 0.0821</em>atm.L/mol.K
Concentration = (0.90g)*(1mol/58.4g/0.100mL) = 0.154mol/L
Molar mass= Concentration*i
Osmotic pressure = Molar mass *the ideal gas constant*T
OP = (0.154)*(1.8)*(0.0821)*(310) = 7.055 atm
The reaction is,
H2S + I2 --------------> 2 HI +S
Molar weight of H2S = 34 g per mol
Molar weight of HI =128 g per mol
Molar weight of I2 =254 g per mol
Moles of H2S in 49.2 g = 49.2 /34 mol = 1.447 mol
So according to stoichiometry of the reaction, number of I2 mols needed
= 1.447 mol
The mass of I2 needed = 1.447 mol x 254 g
