Answer: Option A
Explanation:
The size exclusion chromatography is a type of chromatography which is based on the size of the molecules.
The solution is separated based on the molecular weight and size. It is usually used the separation of the macro molecules.
The sample carrying the mixture of substances is put into the column and then based and the weight or size the smaller molecules comes first and the larger and heavier molecules comes later.
So, the order will be Option A
Answer:
7.34684 × 10^23 atoms
Explanation:
Well, one mole is basically
6.022 × 10^23 atoms. So 1.22 moles would be
6.022 × 10^23 ⋅ 1.22 atoms.
6.022 × 10^23 ⋅ 1.22 = 7.34684 × 10^23 atoms
<u>Answer:</u> The number of atoms of carbon present in given number of moles are
<u>Explanation:</u>
We are given:
Number of moles of carbon =
According to mole concept:
1 mole of an element contains number of atoms.
So, of carbon will contain = number of atoms.
Hence, the number of atoms of carbon present in given number of moles are
