Gas laws describe and predict the behavior of gases without attempting to explain why they happen

true
false

a 6.0 l sample of nitrogen gas contains 0.50 mole of a gas. if enough gas is added to make a total of 0.75 moles at the same pressure and temperature, what is the resulting total volume of the gas? (4 points)

2.3 l

4.8 l

7.5 l

9.0 l

The gas laws describe and predict the behavior of gases with an explanation and experimental data

So the given statement is False.

2) The volume of gas can be calculated based on Avagadro's law

It states that the volume of a gas is directly proportional or varies with the moles of the gas. Higher the moles more the volume, condition is the pressure and temperature are constants in the two conditions

Thus as here the pressure and temperature of nitrogen gas is kept constant

V α  moles

or

Where

V1 = 6 l

n1 = 0.50 mol

V2 = ?

n2 = 0.75 mol

On putting values

V2 = 6 X 0.75 / 0.5 = 9 L

so resulting volume of the gas will be 9L

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
