Density Formula:
| From: | To: |
Density calculation converts molar mass to density using molar volume. It provides the mass per unit volume of a substance, which is essential for understanding material properties and behavior in various applications.
The calculator uses the density formula:
Where:
Explanation: The formula calculates density by dividing the molar mass of a substance by its molar volume, giving the mass contained in one cubic centimeter.
Details: Density is a fundamental physical property used in material science, chemistry, engineering, and quality control. It helps identify substances, determine purity, and predict material behavior under different conditions.
Tips: Enter molar mass in g/mol and molar volume in cm³/mol. Both values must be positive numbers. The calculator will compute the density in g/cm³.
Q1: What is the relationship between molar mass and density?
A: Density is directly proportional to molar mass when molar volume is constant. Higher molar mass typically results in higher density.
Q2: Why is molar volume important in density calculation?
A: Molar volume represents the space occupied by one mole of substance. Different substances with the same molar mass can have different densities due to variations in molar volume.
Q3: What are typical density values for common materials?
A: Water has density of 1 g/cm³, metals range from 2-20 g/cm³, gases are typically 0.001-0.01 g/cm³, and most solids fall between 1-10 g/cm³.
Q4: How does temperature affect density calculations?
A: Temperature affects molar volume - most substances expand when heated (increased molar volume), resulting in decreased density.
Q5: Can this calculator be used for all states of matter?
A: Yes, but molar volume values vary significantly between solids, liquids, and gases. Ensure you use appropriate molar volume for the substance's state.
