0.32 moles
You just do 14/ 44.01 (the atomic mass of carbon + oxygen's atomic massX2)
mass MgCl₂ = mol x MM MgCl₂ = 0.05 x 95.211 g/mol = 4.76 g
mass Cl in MgCl₂ :
= (2 x AM Cl)/MM MgCl₂ x mass MgCl₂
= (2 x 35.5 g/mol)/95.211 g/mol x 4.76
= 3.55 g
% mass Cl in the mixture :
= (mass Cl / mass mixture) x 100%
= 3.55 / 9.8 x 100%
= 36.22%
Explanation:
Dipole moment is defined as the measurement of the separation of two opposite electrical charges.
is a bent shaped molecule with a dipole moment of 1.87.
is also a bent shaped molecule with a dipole moment of 1.10.
is a also a bent shaped molecule and has a negligible dipole moment.
has a dipole moment of 0.29.
Therefore, given molecules are arranged according to their increasing dipole moment as follows.
