Answer:

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)

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}](https://img.qammunity.org/2023/formulas/chemistry/high-school/sxti16rryqj5ymbwi0xh1obiusaxcc1ui6.png)
