Answer 1

`\huge\boxed{\sf n = 7.36 \ mol}`

Step-by-step explanation:

Given Data:

Volume = v = 42.19 L

Pressure = P = 428.792 kPa = 4.23 atm

Temperature = 27.871 °C + 273 = 300.871 K

R = the gas constant = 0.08206 L atm K⁻¹mol⁻¹

Required:

No. of moles = n = ?

Formula:

nRT = Pv

Solution:

Rearranging formula

`\displaystyle n = (Pv)/(RT) \\\\n = ((4.23)(42.19))/((0.08206)(300.871)) \\\\n = (181.467)/(24.69) \\\\n = 7.36 \ mol\\\\\rule[225]{225}{2}`
