law of combining volumes (gay-lussac)

gasses react in specific whole number ratios by volume at constant T and P

<p>gasses react in specific whole number ratios by volume at constant T and P</p>
2
New cards

condition of volume ratio

ONLY for gasses, does not work for solids or liquid

3
New cards

avagadro’s law/hypothesis

equal volumes of gas (same T and P) consist of equal numbers of particles, The number of moles of gas is proportional to its volume at constant temperature and pressure

<p>equal volumes of gas (same T and P) consist of equal numbers of particles, <span>The number of moles of gas is proportional to its volume&nbsp;at constant temperature and pressure</span></p>

New cards

avagadro’s law derrived equation

n1/n2 = V1/V2

<p>n<sub>1</sub>/n<sub>2</sub> = V<sub>1</sub>/V<sub>2</sub></p>
5
New cards

definition of mV

We define Molar Volume as the volume of gas at a particular temperature and pressure consisting of one mole of gas

6
New cards

molar volume formula

mV = V/n

7
New cards

STP of molar volume

mV = 22.4 L/mol

8
New cards

SATP of molar volume

mV = 24.8 L/mol

9
New cards

Density of an ideal gas

Dgas = mm/mV, this ONLY works for gasses

<p>D<sub>gas</sub> = mm/mV, this ONLY works for gasses</p>

how to convert g/L to g/mL

divide by 1000 since the conversion is happening in the denominator
