hahas . well now back to yur thread. yu see yur top ranks for yur subjects. my advice is to maximise on lower ranked subjects, also to achieve a high UAI/ATAR English is the key subject, unfortunately im not doing too well in it :'(
n = m / mm
n = moles (mol)
m = mass (g)
mm = molar mass
v = n * mv
v = volume of gas (L)
n = moles (mol)
mv = molar volume (24.79L at 298.15K and 100kPa) or (22.71 at 273.15K and 100kPa)
c = n / v
c = concentration/molarity (molL^-1)
n = moles (mol)
v = volume (L)
pH = - log...
