What is the mass of 5 moles of Fe2O3? This question delves into the fundamental concept of molar mass, a cornerstone of chemistry that enables us to quantify the mass of substances based on their chemical composition. By exploring the relationship between molar mass and the number of moles, we gain a deeper understanding of the composition and properties of chemical compounds.
Molar mass, expressed in grams per mole (g/mol), represents the mass of one mole of a substance. Understanding molar mass is crucial for various chemical calculations, including determining the mass of a given number of moles of a substance. In this context, we will determine the mass of 5 moles of Fe2O3, an iron oxide compound commonly used in industrial applications.
What is the Mass of 5 Moles of Fe2O3?
The mass of a substance can be determined using its molar mass and the number of moles present. In this article, we will discuss the concept of molar mass, calculate the molar mass of Fe2O3, and determine the mass of 5 moles of Fe2O3.
Understanding Molar Mass
Molar mass is the mass of one mole of a substance. It is expressed in grams per mole (g/mol). The molar mass of an element is the mass of one mole of that element, while the molar mass of a compound is the sum of the molar masses of its constituent elements.
Relationship between Molar Mass and Number of Moles, What is the mass of 5 moles of fe2o3
The number of moles of a substance is equal to its mass divided by its molar mass. Conversely, the mass of a substance is equal to its number of moles multiplied by its molar mass.
Calculating the Molar Mass of Fe2O3
Fe2O3 is a compound composed of iron (Fe) and oxygen (O). The molar mass of Fe2O3 can be calculated as follows:
- Molar mass of Fe = 55.845 g/mol
- Molar mass of O = 16.00 g/mol
- Molar mass of Fe2O3 = (2 x 55.845 g/mol) + (3 x 16.00 g/mol) = 159.69 g/mol
Determining the Mass of 5 Moles of Fe2O3
To determine the mass of 5 moles of Fe2O3, we use the following formula:
Mass = Number of moles x Molar mass
Substituting the values we have:
Mass = 5 moles x 159.69 g/mol = 798.45 g
Applications of Molar Mass
Molar mass is a fundamental concept in chemistry and has numerous applications, including:
- Determining the amount of substance in a sample
- Calculating the concentration of solutions
- Balancing chemical reactions
- Predicting the products of chemical reactions
