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?

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

Explanation:

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

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 =

50.23 i believe is correct but don't quote me on that.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
