Explanation:

Isotopes -

For some elements , there are various forms possible , which have different number of neutron and same number of protons , are referred to as the isotopes .

The three isotopes possible for the element hydrogen are -

Protium , Deuterium and Tritium .

Where ,

  • Protium has one electron , one proton and zero neutron.
  • Deuterium has one electron , one proton and one neutron.
  • Tritium has one electron , one proton and two neutron.

If a sample contains 70.0 % of the R enantiomer and 30.0 % of the S enantiomer, what is the enantiomeric excess of the mixture?
NeTakaya

Answer:

the enantiomeric excess of the mixture is 40%

Explanation:

The computation of the enantiomeric excess of the mixture is shown below:

As we know that

= |\frac{R - S}{R + S} |\times 100\\\\= |\frac{70 - 30}{70 + 30}| \times 100\\\\= 40\%

Hence, the enantiomeric excess of the mixture is 40%
