How Many Moles of Iron Are Contained in 1.75 Kilograms?
In the realm of chemistry, converting mass to moles is a fundamental skill that helps in understanding the composition of substances at a molecular level. Let's explore how to determine the number of moles of iron in 1.75 kilograms through a step-by-step process.Understanding the Basics
Before diving into the calculations, it's essential to grasp a few key concepts related to moles and atomic masses. The mole is a unit of quantity in chemistry, used to express amounts of a chemical substance. The atomic mass of iron is approximately 55.85 grams per mole (g/mol).Step 1: Convert Kilograms to Grams
First, we need to convert the given mass of iron from kilograms to grams. The conversion factor is 1 kilogram (kg) equals 1000 grams (g).
1.75 kg Fe × 1000 g/1 kg 1750 g
Step 2: Apply the Mole Calculation Formula
The formula to convert mass to moles is:
n m/M where n moles, m mass (in grams), and M molar mass (in grams per mole).
Substituting the values into the formula:
n 1750 g Fe / 55.85 g Fe/mol Fe 31.29 moles
Conclusion
Therefore, there are approximately 31.29 moles of iron in 1.75 kilograms of iron.
