Question

How many air molecules are in a 4.57×3.66×3.05 m³ room? Assume atmospheric pressure of 1.00 bar, a room temperature of 20.0 °C, and ideal behavior.

Express your answer using three significant figures.

Answer 1

Here is the answer!

Step-by-step explanation:

So, there are 2093 moles of air inside the room. We know that 1 mol of air = 6.023 × 10 23 number of air molecules. Hence, there are 1.261 × 10 27 number of air molecules.
