1. What is a 10 ml Volumetric Flask?

Definition: A precision glassware designed to contain exactly 10 ml of liquid at a specified temperature (usually 20°C).

Purpose: Used in laboratories for preparing standard solutions with high accuracy in analytical chemistry.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( m \) — Mass of solute (grams)
• \( C \) — Concentration (mol/L)
• \( V \) — Volume (10 ml = 0.01 L)
• \( M \) — Molar mass of solute (g/mol)

Explanation: Calculates the precise mass of solute needed to prepare a solution of specific concentration in a 10 ml flask.

3. Importance of Precise Measurements

Details: Volumetric flasks provide the highest accuracy for solution preparation, crucial for quantitative analysis and standardization.

4. Using the Calculator

Tips: Enter the desired concentration in mol/L and the solute's molar mass in g/mol. The calculator will determine the exact mass to weigh.

5. Frequently Asked Questions (FAQ)

Q1: Why is the volume fixed at 10 ml?
A: Volumetric flasks come in standard sizes. This calculator is specifically for the 10 ml size.

Q2: What temperature is the volume calibrated for?
A: Typically 20°C, as this is the standard reference temperature for glassware calibration.

Q3: How accurate are 10 ml volumetric flasks?
A: Class A flasks typically have ±0.02 ml tolerance, while Class B have ±0.04 ml.

Q4: Can I use this for non-aqueous solutions?
A: Yes, but account for density differences if extreme precision is needed.

Q5: How should I fill the flask?
A: Fill to the calibration mark at eye level for maximum accuracy.
