To determine the number of gas particles in the vessel we add all of the components of the gas. For this, we need to convert the mass to moles by the molar mass. Then, from moles to molecules by the avogadro's number.
1.50x10^-6 ( 1 / 28.01) (6.022x10^23) = 3.22x10^16 molecules CO
6.80x10^-6 ( 1 / 2.02) (6.022x10^23) = 2.03x10 18 molecules H2
Totol gas particles = 2.05x10^18 molecules
Answer:
4202.1 K
Explanation:
From;
PV=nRT
P= pressure of the gas = 18.5 bar
V = volume of the gas = 115L
n= number of moles of the gas = 6.1 mole
T= temperature of the gas = ?
R = gas constant = 0.083 L⋅bar⋅K−1⋅mol−1
T = PV/nR
T = 18.5 * 115/6.1 * 0.083
T = 2127.5/0.5063
T= 4202.1 K
