Question

If 5.50 mol of a gas occupies 230 L at constant temperature and pressure, how many moles are there if the volume is decreased to 176 L?

Answer 1

4.21 moles are the moles of the gas when the volume decreases

Step-by-step explanation:

Based on Avogadro's law, the moles of a gas are proportional to its volume under pressure and temperature constants. The formula is:

`(V_1)/(n_1) =(V_2)/(n_2)`

Where V₁ is initial volume (230L)

n₁ is initial moles (5.50mol)

V₂ is final pressure (176L)

And n₂ are final moles:

176L * 5.50mol / 230L = n₂ =

4.21 moles are the moles of the gas when the volume decreases
