4.4 mol nitrogen.<br><br> VN2 = ____L
Arlecino [84]

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

if the amount of gas is decreased and the temperature and pressure stay constant what will be the effect on its volume
Leviafan [203]

Answer:

Volume will decreased by decreasing the amount of gas.

Explanation:

The amount of gas and volume are directly related to each other. By decreasing the amount of gas volume will decrease by keeping the temperature and pressure constant.

Mathematical expression:

V ∝ n

V = Kn

we put the K by removing the sign of proportionality.

K = proportionality constant

n = amount of gas

V = volume of gas

The volume- amount relation is called Avogadro law.

By increasing the amount of gas volume will also goes to increase.
