# iven each of the following sets of values for three of the gas variables, calculate the unknown quantity.msp;  a . P =  21 . 2 atm : V =  142 mL ; n =   0. 432 mol ; T =   ?  K b . P =   ?  atm ; V =  l . 23 mL  ; n =   0.0 OOl15 mol ; T =  293 K c . P =  755 mm Hg ; V =   ? mL ; n =   0. 473 mol ; T =  131  ° C

Interpretation Introduction

(a)

Interpretation:

To calculate the missing value of temperature of a gas with the help of ideal gas equation.

Concept Introduction:

The ideal gas equation exhibits the relation between pressure, volume and temperature for ideal gas. The ideal gas equation is as given below:

PV = nRT

Here R is gas constant that value is 0.0821 L. atm / K. mol.

Explanation

Given information:

P = 21.2 atm

V = 142 mL = 0.142 L (1mL = 0.01 L)

n = 0.432 mole

Plug the values in ideal gas equation;

PV = nRT

21.2 atm × 0.142 L = 0.432 moles × 0.0821 L. atm / K

Interpretation Introduction

Interpretation Introduction

(c)

Interpretation:

To calculate the missing of volume of gas with the help of ideal gas equation.

Concept Introduction:

The ideal gas equation exhibits the relation between pressure, volume and temperature for ideal gas. The ideal gas equation is as given below:

PV = nRT

Here R is gas constant that value is 0.0821 L. atm / K. mol.
