Answer:
[tex]\huge\boxed{\sf v = 0.017 \ L}[/tex]
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)
[tex]\displaystyle n = \frac{mass}{molar \ mass} \\\\n = \frac{0.08 }{102} \\\\n =0.0008 \ mol[/tex]
Now, Finding volume (v)
Rearranging formula
[tex]\displaystyle v = \frac{nRT}{P} \\\\v = \frac{(0.0008)(0.08206)(292.1)}{1.14} \\\\v = \frac{0.019}{1.14} \\\\v = 0.017 \ L\\\\\rule[225]{225}{2}[/tex]
