Q
avagadro
A
equal volumes of gases contain equal numbers of molecules
2
Q
mole
A
6.02x10^23
number of molecules
3
Q
molar volume
A
the volume of one mole at STP or SATP
4
Q
how do you calculate grams per mole
A
1) write the chemical formula
2) split and add up all molar masses per atom
3) multiply each atom by number of atoms in formula

22
Q
ideal gas
A
hypothetical gas,
- where molecules bounce off each other
- have negligible size
- do not come in contact with each other
23
Q
when is a gas closest to this “ideal gas” state
A
high temperature and low pressure
freer to move
24
Q
ideal gases obey how many gas laws
A
all of them
25
most gases behave
approximately to ideal gases
26
list some things all ideal gases do (4)
- move constantly, in a straight line
- small, mostly empty space
- no force of attraction between molecules
- no transfer of energy
27
average kinetic energy depends on
temperature
28
exceptions of ideal gases
- gases at a low temperature (more of a chance for interaction)
- very high pressure
29
intermolecular
between molecules
30
intramolecular
inside molecules
31
what is the equation for ideal gas law
PV= nRT
32
what laws is the ideal gas law made up of
boyles, charles, and avogadro
33
what does each variable stand for in the IDEAL GAS LAW
```
p- pressure kPa
v- volume L
n- moles mol
R- constant so units are balanced 8.314 kPa L/K mol
T- temperature K
```
