###### Question details

1.

a) Show how you would calculate the number density of boron-10 in natural (elemental) boron with elemental density, ρ (g/cm3). Use numbers for all terms except the density.

mass (10B) = 10.0129 amu and mass (11B) = 11.0093 amu

natural isotopic abundances are 19.9% 10B and 80.1% 11B

b) Show how you would calculate the number density of boron-10 in a mixture of boron (containing 19.9 weight % boron-10 and 80.1 weight % boron-11) with mixture density, ρ (g/cm3). Use numbers for all terms except the density.
