Solution Preparation Table (Amount & Scale)

Solution preparation calculator for reagent mass to prepare solution, with a scale-up table (×2/×10) in one step.

This tool only calculates required amounts. It does not provide hazardous procedures. Follow SDS and your facility rules.

Input (solute, concentration, volume, purity)

Scaled final volume

×2 doubles both final volume and required amounts. Shows scaled volume next to factor.

Solute table

Add rows to handle multiple components in a mixed solution.

采购 Component Formula/MW 浓度 Purity% 密度 备注 操作

Example: NaCl or 58.44 (if formula cannot be parsed, enter molar mass directly)

Example: 98 (=98%). Empty is treated as 100%.

高级

Adjust rounding, auto-unit switching, scale table factors, and liquid volume output.

Comma-separated (example: 0.5,1,2,5,10)

Solution Preparation Table (Amount & Scale)

Output (required amounts, scale table, print/CSV)

Missing inputs / cautions

    Required amount table (scaled)

    This table already reflects the scale factor.
    Component 浓度 Molar mass Required moles Required mass Required volume Purity 提示

    Add a solute to show required amounts.

    Scale-up table (compare factors)

    Enter multiple factors to compare per-component required mass across scales.

    Enter concentration and final volume to show the scale table.

    Volumetric flask rounding suggestions

    Suggests standard volumes and recalculates required amounts for those volumes.

    Notes (included in print/CSV)

    Print memo

    Printing outputs only the table, notes, and safety notice.

    常见问题

    Purity is not 100%.

    You can enter purity (e.g., 98%) and the required mass/volume is corrected automatically.

    Multiple solutes in one solution?

    Add rows to handle multiple components. Each solute is calculated individually.

    Rounding to standard flask volumes?

    The tool suggests standard volumes (10/25/50/100 mL, etc.) and recalculates amounts for those volumes.

    I do not know the chemical formula.

    Enter the molar mass (g/mol) directly.

    Safety notes (SDS & labeling)

    • This tool only supports amount calculation and does not describe hazardous procedures.
    • Follow SDS (Safety Data Sheet) and your institution's safety rules.
    • Label contents (components, concentration, solvent), date, preparer, and hazards after preparation.
    • Purity is treated as the active ingredient fraction for mass correction.
    • Actual required amounts may vary with density, purity, hydrates, etc. Verify for critical use.
