The atomic mass is the average of the isotopes of the element meaning most averages of isotopes will not be whole numbers
I believe it would be 7.731. x 10^5? That is if they want you to evaluate.
This will be classified as light on the API scale due to the large percentage of lighter fractions such as paraffins and naphthenes.
Answer: The correct option is heterogeneous mixture whose components are attracted differently to a magnet.
Explanation: There are two types of mixtures:
1) Homogeneous mixtures: In these mixtures, the particles are uniformly distributed throughout the mixture. These particles cannot be separated.
2) Heterogeneous Mixtures: These are the mixtures where the particles are visible separated and are not-uniformly distributed. These particles can be separated easily.
If magnet is used to separate the components of a mixture, the heterogeneous mixtures will only get separated.
To separate the components by a magnet, the components of a mixture should attract the magnet differently. One component should attract the magnet and another should not. Hence, they can be easily separated.
Your answer is going to be b
