AMOUNT OF SUBSTANCE Flashcards
1
Q
EMPIRICAL FORMULA
A
simplest whole number ratio of atoms of each element in a compound
2
Q
Mole equation for solutions and units
A
mol = concentration(mol/dm3) x volume(dm3)
3
Q
n = m/M
A
mol = mass/molecular mass
4
Q
WHAT IS THE STANDARD RTP
A
20 degrees
101 kPa
5
Q
IDEAL GAS EQUATION AND UNITS
A
pV = nRT
pressure(Pa) x Volume(m3) = mol x 8.31 x Temperature(K)
6
Q
PERCENTAGE YIELD EQUATION
A
percentage yield = actual yield/theoretical yield x 100
7
Q
ATOM ECONOMY EQUATION
A
= molar mass of desired products/ molar mass of all products x 100
8
Q
Avogadro’s number
A
6.02 x 10^23
9
Q
Why is high atom economy important
A
Reduces waste products( bad for environment)
Is more sustainable
Less by products that take time to separate and dispose of
