Let's break down the problem step by step.
First, we need to convert the volume of the room from cubic meters to liters. We know that 1 cubic meter is equal to 1000 liters, so:
120 cubic meters × 1000 liters/cubic meter = 120,000 liters
Next, we need to find the volume of nitrogen in the room. Since nitrogen makes up 80% of the air, we can set up the following equation:
Volume of nitrogen = Total volume of air × Percentage of nitrogen
= 120,000 liters × 0.80
= 96,000 liters
Therefore, there are **96,000 liters** of nitrogen in the room.
