Introduction

Sucrose, commonly known as table sugar, is a disaccharide composed of glucose and fructose molecules. It is a vital component of many food products and plays a significant role in various industrial applications. Understanding the molar mass of sucrose is essential in chemistry, as it helps in calculating the amount of substance required for a particular reaction or process. In this article, we will calculate the molar mass of sucrose and provide a detailed explanation of the concept.

What is Molar Mass?

Molar mass, also known as molecular mass, is the mass of one mole of a substance. It is a fundamental concept in chemistry that helps in understanding the properties and behavior of substances. The molar mass of a substance is calculated by summing the atomic masses of its constituent atoms. The atomic mass of an element is the mass of one atom of that element, expressed in units of grams per mole (g/mol).

Calculating the Molar Mass of Sucrose

To calculate the molar mass of sucrose, we need to sum the atomic masses of its constituent atoms. The molecular formula of sucrose is C12H22O11C_{12}H_{22}O_{11}. We will use the atomic masses of carbon (C), hydrogen (H), and oxygen (O) to calculate the molar mass of sucrose.

The atomic masses of the elements are:

  • Carbon (C): 12.01 g/mol
  • Hydrogen (H): 1.008 g/mol
  • Oxygen (O): 16.00 g/mol

Step 1: Calculate the Mass of Carbon Atoms

The molecular formula of sucrose contains 12 carbon atoms. We will calculate the mass of these carbon atoms by multiplying the atomic mass of carbon by 12.

Mass of carbon atoms = 12.01 g/mol x 12 = 144.12 g/mol

Step 2: Calculate the Mass of Hydrogen Atoms

The molecular formula of sucrose contains 22 hydrogen atoms. We will calculate the mass of these hydrogen atoms by multiplying the atomic mass of hydrogen by 22.

Mass of hydrogen atoms = 1.008 g/mol x 22 = 22.176 g/mol

Step 3: Calculate the Mass of Oxygen Atoms

The molecular formula of sucrose contains 11 oxygen atoms. We will calculate the mass of these oxygen atoms by multiplying the atomic mass of oxygen by 11.

Mass of oxygen atoms = 16.00 g/mol x 11 = 176.00 g/mol

Step 4: Calculate the Molar Mass of Sucrose

To calculate the molar mass of sucrose, we will sum the masses of its constituent atoms.

Molar mass of sucrose = Mass of carbon atoms + Mass of hydrogen atoms + Mass of oxygen atoms = 144.12 g/mol + 22.176 g/mol + 176.00 g/mol = 342.296 g/mol

Rounding the Answer

We are asked to round the answer to the nearest whole number. Therefore, the molar mass of sucrose is approximately 342 g/mol.

Conclusion

In conclusion, the molar mass of sucrose (C12H22O11C_{12}H_{22}O_{11}) is approximately 342 g/mol. This value is essential in understanding the properties and behavior of sucrose in various chemical reactions and processes. We hope this article has provided a clear and concise explanation of the concept of molar mass and its application in calculating the molar mass of sucrose.
