3.4 - Molar Volume Flashcards
What do you call the mass of one mole of substance?
The molar mass.
How do you find molar mass for monoatomic elements?
Use relative atomic masses listed on periodic table, expressed in g/mol
How do you find molar mass for diatomic elements?
Double the relative atomic mass from the periodic table, expressed in g/mol
How do you find the molar mass for compounds?
Add up the relative atomic mass of each atom, expressed in g/mol
You can use molar mass, a derived unit, as a conversion factor between what?
Moles and mass.
What do you call the volume occupied by one mole of a substance’s particles, at a given temperature and pressure?
Molar volume.
T or F, the particles are close enough in solids and liquids that the matter is incompressible.
True
The size and spacing of a substance’s particles affect its molar volume in which state(s)
Solid and liquid.
The size of particles doesn’t affect the molar volume in which state(s)?
Gas.
Due to thermal expansion, the volume taken up by one mole of particles will depend on the _____ of those particles.
Temperature.
Thermal expansion is more significant in which state(s)?
Gas.
Pressure and the separation of a matter’s particles (mostly gases) are directly or inversely related?
Inversely.
Molar volume is directly or inversely proportional to temperature?
Directly.
Molar volume is directly or inversely proportional to pressure?
Inversely.
What is Avogadro’s famous hypothesis to explain why adding up the volumes of gasses don’t always add the way we expect?
Equal volumes of all gases, at the same temperature and pressure, contain the same number of particles.
