equations, conversions + definitions Flashcards
1
Q
ideal gas equation
A
PV = nRT
pressure (Pa) x volume (m³) = mol x gas constant x temperature (K)
2
Q
equation for atom economy
A
(Mr of desired products / Mr of all reactants) x 100
3
Q
calculating number of moles
A
number of moles = mass (g) / Mr
4
Q
percentage yield formula
A
(actual yield / theoretical yield) x 100
5
Q
calculating concentration
A
concentration (mol/dm³) = no. moles / volume (dm³)
6
Q
standard conditions for measuring enthalpy changes?
A
pressure = 100kPa temperature = 298K
7
Q
calculating enthalpy change (q)
A
q = mass of substance x specific heat capacity x temperature change
q = mc(change)T
