Answer:

Number of moles of H₂S gas = 0.0183 moles

Note: The question is incomplete. The complete question is given below:

How many moles of hydrogen sulfide H2S are contained in a 327.3 mL bulb at 48.1°C if the pressure is 149.3 kPa?

Explanation:

The following values are given in the question :

Volume of H₂S gas = 327.3 M = 0.3273 L

Temperature of gas = 48.1°C = (273.15 + 48.1) K = 321.25 K

Pressure of gas = 149.3 kPa

1 kPa = 0.00987 atm; 149.3 kPa = 149.3 × 0.00987 atm = 1.474 atm

Molar gas constant, R = 0.0821 liter·atm/mol·K.

number of moles, n = ?

Using PV = nRT

n = PV/RT

n = (0.3273 × 1.474)/(0.0821 × 321.25)

n = 0.0183 moles

Therefore, number of moles of H₂S gas = 0.0183 moles
