1. What is a 50 ml Volumetric Flask?

Definition: A precision glassware designed to contain exactly 50 ml of liquid at a specified temperature (usually 20°C).

Purpose: Used in laboratories to prepare solutions with high accuracy and precision.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Mass} = C \times V \times M \]

Where:

\( C \) — Solution concentration (mol/L)
\( V \) — Volume of flask (0.050 L)
\( M \) — Molar mass of solute (g/mol)

Explanation: The calculator determines how much solute (in grams) is needed to prepare a solution of specific concentration in a 50 ml flask.

3. Importance of Volumetric Flask Calculations

Details: Accurate solution preparation is critical for experiments, quality control, and standardized testing in chemistry and biology.

4. Using the Calculator

Tips: Enter the desired concentration in mol/L and the solute's molar mass in g/mol. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the volume fixed at 50 ml?
A: Volumetric flasks are manufactured to contain precise volumes. This calculator specifically handles the common 50 ml size.

Q2: What temperature is the volume calibrated for?
A: Typically 20°C, as glassware expands or contracts slightly with temperature changes.

Q3: How accurate are volumetric flasks?
A: Class A flasks are typically ±0.05 ml accurate for 50 ml size.

Q4: Can I use this for non-aqueous solutions?
A: Yes, but density corrections may be needed for very precise work with organic solvents.

Q5: How should I prepare the solution?
A: Dissolve the calculated mass in less than 50 ml solvent, then dilute to the mark while mixing.
