Calculating the Mass of Sucrose in Grams for 0.105 Mole

In this article, we will explore how to calculate the mass of sucrose in grams from a given number of moles. Sucrose, also known as table sugar, has a well-defined molar mass. Understanding this concept is essential for various scientific and industrial applications. We will break down the steps to find the mass of 0.105 moles of sucrose, a common scenario in chemistry and laboratory settings.

Understanding Molar Mass and its Importance

The molar mass of a substance is the mass of one mole of its molecules and is expressed in grams per mole (g/mol). For sucrose, the molar mass is approximately 342.296 grams per mole. This value is a fundamental constant that allows us to convert between moles and grams in chemical calculations.

Step-by-Step Calculation

Let's use the given information to calculate the mass of 0.105 moles of sucrose. Here is a straightforward step-by-step process to find the answer:

Molar Mass of Sucrose: The molar mass of sucrose (C12H22O11) is 342.296 g/mol. Given Information: We have 0.105 moles of sucrose. Required Calculation: The mass of sucrose in grams can be calculated by multiplying the number of moles of sucrose by the molar mass of sucrose:

Mass of sucrose (grams) Number of moles × Molar mass of sucrose (g/mol)

Mathematical Calculation:

To calculate it:
0.105 moles × 342.296 g/mol 35.94156 grams
Rounding to three significant figures, we get: 35.9 grams

Dimensional Analysis and Consistency

To ensure dimensional consistency, we multiply the number of moles by the molar mass expressed in grams per mole. This product gives the mass in grams, confirming our units are correct.

Conclusion

The mass of 0.105 moles of sucrose is approximately 35.9 grams. Understanding this calculation is crucial when working with sucrose or other substances in chemical or biological laboratories. By knowing the molar mass and applying it to a given number of moles, we can easily determine the mass of the substance in grams.
