module 2: 3.3 moles and volumes Flashcards
moles and volumes 2.1.3
the cubic centimeter (cm^3) or millimetre (ml)
1 cm^3 = 1 ml
the cubic decimetre (dm^3) or litre (l)
1 dm^3 = 1000 cm^3 = 1000 ml = 1 litre
volume triangle
amount (n) {mol} = concentration (c) {mol dm^3} * volume (V) {dm^3}
co * vo
define standard solution
standard solution is a solution of a known concentration
define molar gas volume
molar gas volume is the volume per mole of gas molecules at a stated temp and pressure
RTP temp and pressure
20 degrees Celsius and 101 kPA (1 atm) pressure
what is the molar gas volume at RTP
24,000 cm^3 or 24 dm^3 mol^-1
ideal gas equation
pV = nRT
pressure (p) {Pa} * volume (V) {M^3} = amount of gas molecules (n) {mol} * ideal gas constant (R) {8.31 J mol^-1 K^-1} * temperature (T) {kelvin, K, 273}
