Chapter 10.3, Problem 10.7CYU
Textbook Problem

At 1.00 atm and 25 °C, the density of dry air is 1.18 g/L. If the air is heated to 55 °C at constant pressure, what is its density?

Expert Solution
Interpretation Introduction


The density of air should be determined.  The density of air at 1atmand25°C is given and the air is heated to 55°C

Concept Introduction:

Density of a gas can be find out with the help of ideal gas equation which is


n in the given equation can be written as mM since amount of any substance is given by dividing mass with molar mass.


Explanation of Solution

We know that density=PMRT
