Really really confuded please help Watch
Calculate the relative molecular mass of Q
K.E. = 1/2 m v2
Where the mass=mass(kg) and v=speed (m s -1 )
The avagardo constant L =6.022x1023 mol-1
do you understand how a TOF mass spectrometer works?
can you calculate the mass of the ion in SI units (kg)?
can you convert from kg to grams?
do you understand that 'relative atomic mass' means 'mass expressed in atomic mass units
can you convert between g and amu (using Avogadro's constant)?
