The element that has the higher number of atoms is to be determined in given elements. Concept Introduction: The molar mass of a substance is the mass of that substance present in one mole of it. A mole is a quantity used to express a very large number of atoms or molecules. One mole of a substance is equal to 6.022 × 10 23 , that is, Avogadro’s number . The moles of a substance are expressed as: n = m M Here, m is the mass of the substance, M is the molar mass, and n is the number of moles. The mass of a substance is given by the expression m = M n The relationship between moles of a substance and number of atoms can be expressed as 1 mole = 6 .022 × 10 23 atoms To convert moles into number of atoms, conversion factor is 6.022 × 10 23 atoms 1 mol .

Interpretation Introduction
Interpretation:
The element that has the higher number of atoms is to be determined in given elements.
Concept Introduction:
The molar mass of a substance is the mass of that substance present in one mole of it.
A mole is a quantity used to express a very large number of atoms or molecules. One mole of a substance is equal to 6.022×1023, that is, Avogadro’s number.
The moles of a substance are expressed as: n=mM
Here, m is the mass of the substance, M is the molar mass, and n is the number of moles.
The mass of a substance is given by the expression m=Mn
The relationship between moles of a substance and number of atoms can be expressed as 1 mole = 6.022×1023atoms
To convert moles into number of atoms, conversion factor is 6.022×1023 atoms1 mol.

1) The isoamyl acetate report requires eight paragraphs - four for comparison of isoamyl alcohol and isoamyl acetate (one paragraph each devoted to MS, HNMR, CNMR and IR) and four for comparison of acetic acid and isoamyl acetate ((one paragraph each devoted to MS, HNMR, CNMR and IR.
2) For MS, the differing masses of molecular ions are a popular starting point. Including a unique fragmentation is important, too.
3) For HNMR, CNMR and IR state the peaks that are different and what makes them different (usually the presence or absence of certain groups). See if you can find two differences (in each set of IR, HNMR and CNMR spectra) due to the presence or absence of a functional group. Include peak locations. Alternatively, you can state a shift of a peak due to a change near a given functional group. Including peak locations for shifted peaks, as well as what these peaks are due to. Ideally, your focus should be on not just identifying the differences but explaining them in terms of…
