Question

The volume of 1 g each of methane ($C{H}_4$), ethane ($C_2{H}_6$) , propane ($C_4{H}_{1}0$) was measured at 350 K and 1 atm. What is the volume of butane

• A. 495 cm³
• B. 600 cm³
• C. 900 cm³
• D. 1700 cm³

Answer 1

The correct option is A

495 cm³

V = $\frac{nRT}{P}$ = $\frac{m}{M}$ $\frac{RT}{P}$ = $\frac{1}{58}$ $\times$ $\frac{0.82\times 350}{1}$ = 0.49 Lit

= 495 ${cm}^3$
