According to Avogadro's Law, when the number of moles doubles, the volume
a. is squared.
b. quadruples.
c. also doubles.
d. is cut in half.
I think C, but don't understand it
Yes, C is right. The following will show you why that is right.
PV = nRT
Say P, R, T are some constant numbera. Just for the fun of it let's say RT/P = 10 so now that equation is
V = 10n. So if n = 1 (that's 1 mol) then V is 10
If n = 2 mols then V is 20. What happened to V when we doubled mols (that's n). V went from 10 to 20. It doubled, This should make it plain why that happens.
According to Avogadro's Law, when the number of moles doubles, the volume also doubles. This means that if you have twice as many moles of a gas, the volume of the gas will also be twice as large. So, the correct answer is option c: also doubles.
Avogadro's Law states that, at constant temperature and pressure, equal volumes of gases contain an equal number of molecules. According to this law, when the number of moles of a gas doubles, the volume will also double. This means that the answer is option C.
To understand this concept, let's break it down. Moles are a unit of measurement used to quantify the amount of a substance. In the context of gases, moles represent the number of gas molecules present.
Avogadro's Law tells us that when we double the number of gas molecules (moles), an equal number of new gas molecules is added, resulting in twice the original amount. Since the volume of a gas is directly proportional to the number of molecules, when the number of moles doubles, the volume of the gas also doubles.
It's important to note that Avogadro's Law only holds true when the temperature and pressure remain constant.
