Molecular formula of compound when 5.28 mg of sample of compound yields 18.13 mg of CO 2 has to be determined. Concept Introduction: Mole is S.I. unit. The number of moles is calculated as ratio of mass of compound to molar mass of compound. Molar mass is sum of the total mass in grams of all atoms that make up mole of particular molecule that is mass of 1 mole of compound. The S.I unit is g/mol . The expression to relate number of moles, mass and molar mass of compound is as follows: Number of moles = mass of the compound molar mass of the compound Empirical formula represents the simplest positive integer ratio of atoms in the compound. It only gives proportions of elements in compound. Molecular formula consists of chemical symbols for the respective elements followed by numeric subscript that denotes the number of atom of each element present in molecule.

Interpretation Introduction

Interpretation:

Molecular formula of compound when 5.28 mg of sample of compound yields 18.13 mg of CO2 has to be determined.

Concept Introduction:

Mole is S.I. unit. The number of moles is calculated as ratio of mass of compound to molar mass of compound.

Molar mass is sum of the total mass in grams of all atoms that make up mole of particular molecule that is mass of 1 mole of compound. The S.I unit is g/mol.

The expression to relate number of moles, mass and molar mass of compound is as follows:

Number of moles=mass of the compoundmolar mass of the compound

Empirical formula represents the simplest positive integer ratio of atoms in the compound. It only gives proportions of elements in compound. Molecular formula consists of chemical symbols for the respective elements followed by numeric subscript that denotes the number of atom of each element present in molecule.
