Answer to Question #157363 in General Chemistry for maricar padilla

Question

What is the molar volume of an ideal gas if the pressure is 125 KPa at 300 K. If the experimental volume of the gas in a cube with 1.5 moles is 5 x 10-4 m3/mol, what is the compression factor?

Answer 1

P= 125KPa , no. of moles(n) = 1.5 moles

T = 300K , V = ?

PV = n RT

125 × V = 1.5 × 0.082057 × 300

V = 0.2954L = 0.0002954m³/mol

compression factor = $\frac{5×10^-⁴}{0.0002954}$

= 1.69
