M - moles of known
M - moles of unknown
A - answer
3
Q
gas volumes
A
volume/24 (in dm3)
4
Q
moles 1
A
moles = mass/ mr
5
Q
moles 2
A
moles = concentration x volume
6
Q
ideal gas equation
A
pressure x volume = moles x temperature x gas constant
7
Q
energy change
A
energy change = mass x specific heat capacity x change in temp
divide my moles for enthalpy change
