Answer
Molecular formula of sulfur is S8
Work Step by Step
from Ideal gas law: PV = nRT
P = 93.2 kPa (0.9198125 atm)
R: gas constant (0.0821 L-atm / mole-K)
T: gas temperature in Kelvin (293.15)
, but n = m/M .........m: is mass of gas........... M: molar mass of gas
PV = (m/M) RT
MPV =mRT ..................... M= (m/V)(RT/P)
m/V = d, while d is denisty of gas (mass/volume)
so M = (dRT)/P
= 3.710 × 0.0821 × 773.15 / 0.9198125
= 256 g
n of gas = Mass of gas / Molar mass of sulfur
= 256/16
= 8
