Explanation Molar mass is equal to the sum of the masses of the atoms which are present in the molecule. For example: In H 3 PO 4 , three atoms of hydrogen, one atom of phosphorus and four atoms of oxygen are present. Now, atomic mass of hydrogen = 1 amu Atomic mass of three atoms of hydrogen = 1 amu × 3 = 3 amu Atomic mass of phosphorus = 30

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can b…

Chapter 9, Problem 4CR

Interpretation Introduction

Interpretation:

The definition of molar mass should be determined along with the molar mass of H3PO4, taking as an example.

Concept Introduction:

Molar mass is defined as the mass of molecule or compound which is equal to the addition of the masses of atoms present in the molecule.

As you can see in the picture, the instrument uses a Xe source. Given that the instrument is capable of measuring from 200-800nm, if Xe was not used, what other source(s) could be used? Refer to figure 7-3. How many monochrometers does this instrument have? Why? Trace the light as it goes from the Xenon lamp all the way to the circle just slightly to the right and a little bit down from S4. What do you think that circle is? In class we talked about many types of these, which kind do you think this one is for a fluorimeter? Why? Explain. What is/are some strategy(ies) that this instrument has for dealing with noise that you see present in the optics diagram? Why does a fluorescence cuvette have to be clear on four sides?

Provide steps and thoroughly solve.
