Investigate the molecular masses in this sequence of molecules
and deduce which molecule has been analysed in the mass
spectrometer. Explore the distribution of molecular masses for
various hydrocarbons Which dilutions can you make using only
10ml pipettes? Get some practice using big and small numbers in
chemistry. Many physical constants are only known to a certain
accuracy. Explore the numerical error bounds in the mass of
water and its constituents. How much energy has gone into
warming the planet? Work out the numerical values for these
physical quantities. Work with numbers big and small to estimate
and calculate various quantities in physical contexts. PhysNRICH

solar system Can you suggest a curve to fit some experimental
data? Can you work out where the data might have come from?
