amount of substance (gasses)

what are gasses and liquids measured in

volume

what is the most common unit of volume in chemistry

dm³

how many dm³ are in a cm³

1dm³ = 1000cm³

what are the 2 volume equations

moles(n)=concentration(c)volume(v)

n=cxv

moles=volume(dm³)/24

moles=volume(cm³)/24000

what is a standard solution

a solution of a known concentration

what is the molar gas volume

the volume per mole of gas at a stated temp and pressure

what is room temp and pressure

20 degrees Celsius/293 degrees K

101kPa

what is the ideal gas equation

pV=nRT

pressure(Pa) x volume(m³) = moles(n) x gas constant(8.314) x temperature(K)

what must you assume when using the ideal gas equation

random motion

elastic collisions

negligible size

no intermolecular forces
