The set of quantities that is required to obtain molar mass of a compound has to be chosen from the given options. Concept Introduction: Sum of atomic masses of all the atoms that are represented in chemical formula of substance is known as formula mass. If atomic mass and chemical formula of a compound is known, then formula mass can be calculated. Molar mass is the mass that is expressed in grams of a substance that is equal to the formula mass of the substance numerically. Molar mass of an element is unique for the particular element. Two natural elements can never have the same molar mass. Mole is defined as the amount of substance that has as many elementary particles as there are atoms in exactly 12 grams of C 6 12 . The relationship between the atomic mass unit and grams unit is, 6.02 x 1023 a m u = 1.00 g o r 1 a m u = 1.66 x 10 − 24 g

Interpretation Introduction

Interpretation:

The set of quantities that is required to obtain molar mass of a compound has to be chosen from the given options.

Concept Introduction:

Sum of atomic masses of all the atoms that are represented in chemical formula of substance is known as formula mass. If atomic mass and chemical formula of a compound is known, then formula mass can be calculated.

Molar mass is the mass that is expressed in grams of a substance that is equal to the formula mass of the substance numerically. Molar mass of an element is unique for the particular element. Two natural elements can never have the same molar mass.

Mole is defined as the amount of substance that has as many elementary particles as there are atoms in exactly 12 grams of C612.

The relationship between the atomic mass unit and grams unit is,

6.02 x 1023 amu = 1.00 g or 1 amu = 1.66 x 10−24 g

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
