Question

7.48 g of Ethanol vapors (C2H6O1) are added to a 501 mL container with a pressure of 35.2 kPa. What is the temperature of the ethanol?

Expert Solution

Step 1-Introduction

The relation among the parameters such as the pressure ( $P$ ) of the gaseous system in 'atm', the volume of the gas ( $V$ ) in 'L', the temperature ( $T$ ) of the gaseous system in 'K', the number of moles of the system ( $n$ ) in 'mol' unit is furnished as follows:

$\begin{array}{rcl} P V & = & n R T \\ T & = & \frac{P V}{n R} . . . (1) \end{array}$

The number of moles of the gaseous system ( $n$ ) is related to the ratio of the mass to molar mass.

$n = \frac{M a s s}{M o l a r m a s s} . . . (2)$
