Answer:


\huge\boxed{\sf v = 0.017 \ L}

Step-by-step explanation:

Given Data:

Mass = m = 0.08 g

Molar mass of C₂H₂F₄ = (12×2) + (1×2) + (19×4)

= 24 + 2 + 76 = 102 g/mol

Pressure = P = 1.14 atm

Temperature = T = 19.1 °C + 273 = 292.1 K

Gas Constant = R = 0.08206 L atm K⁻¹ mol⁻¹

Required:

Volume = v = ?

Formula:

Pv = nRT

Solution:

Firstly, finding moles (n)


\displaystyle n = (mass)/(molar \ mass) \\\\n = (0.08 )/(102) \\\\n =0.0008 \ mol

Now, Finding volume (v)

Rearranging formula


\displaystyle v = (nRT)/(P) \\\\v = ((0.0008)(0.08206)(292.1))/(1.14) \\\\v = (0.019)/(1.14) \\\\v = 0.017 \ L\\\\\rule[225]{225}{2}
