1
Q
what is the formula for masses to moles
A
mass = mols x mr
2
Q
what is the formula for solution volume or concertration to moles
A
mols = volume (dm^3) x concerntration
3
Q
what is the formula for gas volume to moles
A
volume (dm^3) = moles x 24
4
Q
how many grams in 1 kg
A
1000g = 1kg
5
Q
how many cm^3 in 1dm^3
A
1000cm^3 = 1dm^3
6
Q
how do you calculate the Ar from isotopic abundancies
A
sum of {isotope % x isotope mass} / 100
7
Q
how do you calculate heat energy transfers
A
q = mass of liquid being heated (g) x specific heat capacity x change in temperature of liquid
