C4 Chemical Calculations Flashcards
1
Q
How do you find relative aromic mass ?
A
(% isotope 1 x mass isotope 1) + (% isotope 2 x mass isotope 2) /100
2
Q
Mole ratio calculations
A
Moles = mass (g)/molar mass (g/mol)
Moles = volume (dm3)/ 24 (dm3/mol) gas
Moles = concentration (mol/dm3) x volume (dm3)
