Answer:
99 L
Explanation:
Step 1: Given data
Moles of nitrogen: 4.4 moles
Step 2: Calculate the volume occupied by 4.4 moles of nitrogen
The volume occupied by a gas depends on other conditions such as pressure (P) and temperature (T). If we have this information, we can calculate the volume of the gas using the ideal gas condition.
P × V = n × R × T
Since the task doesn't inform the conditions, we can assume it is under standard pressure (1 atm) and temperature (273.15 K). At STP, 1 mole of any gas occupies 22.4 L.
4.4 mol × 22.4 L/1 mol = 99 L
Answer:
One way to measure the volume of any irregular object (in your case, a stone) is to submerge it completely under water and measure the change in the height of the water level. This change in the water level (let's say it goes from 50 mL to 65 mL) indicates that the stone has a volume of 15 mL.
