Test 1 - Calculations Flashcards
1
Q
Moles =
A
Mass (g) / Mr
3
Q
Concentration (g/dm3) =
A
mass (g) / volume (dm3)
4
Q
Ideal Gas Equation
A
Pressure (Pa) x Volume (m3) = Moles x Gas Constant (8.31) x Temperature (Kelvin)
PV = nRT
5
Q
Celsius > Kelvin
A
+273
6
Q
cm3 > dm3
A
/ 1000 (one thousand)
7
Q
cm3 > m3
A
/ 1000000 (1 million)
8
Q
atm > Pa
A
x 101,000
9
Q
Volume of gas (dm3) at R.T.P
A
Moles x 24
10
Q
Volume of gas (cm3) at RTP
A
Moles x 24,000
11
Q
Volume of gas (dm3) at S.T.P.
A
Moles x 22.4
12
Q
conc. (g/dm3) > conc. (moles/dm3)
A
/ Mr (bc moles = mass / mr)
13
Q
% yield
A
(mass of product obtained / maximum theoretical mass of product) x100
14
Q
Concentration (mol/dm3)
A
= Moles / Volume (dm3)
