A)192
B)1.92
C)0.192
D)19.2
E)0.0192

To calculate the total pressure in the vessel, we will use the ideal gas law:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. At standard temperature, T = 273.15 K.

First, we need to calculate the total number of moles in the vessel:

n_total = n_CO2 + n_SO2 + n_Ar 
n_total = 2.34 mol + 1.73 mol + 4.50 mol 
n_total = 8.57 mol

Next, we can rearrange the ideal gas law to solve for pressure:

P = nRT/V

Plugging in the values:

P = (8.57 mol)(0.08206 L·atm/mol·K)(273.15 K)/(10.0 L)

P = 19.2 atm

Therefore, the answer is D.
