Calculadora de molaridad para ARN

Convierte la concentración de ARN en ng/uL y el PM a nM.

Introducción

Molarity for RNA Calculator — Convert RNA ng/uL concentration and MW to nM. Enter Concentration (ng/µL), Molecular weight (g/mol) to get an instant, accurate result.

Fórmula

Molarity (nM) = (mass concentration in ng/µL ÷ molecular weight in g/mol) × 10⁶ — the same mass-to-molar conversion as the DNA version, applied to RNA using its molecular weight.

Paso a paso

  1. Enter the Concentration (ng/µL).
  2. Enter the Molecular weight (g/mol).
  3. Click Calculate to see your result instantly.

Ejemplo del mundo real

Example: With Concentration (ng/µL) = 50, Molecular weight (g/mol) = 320500, the Molarity for RNA Calculator gives Molarity Nm: 156.0062.

Preguntas Frecuentes

Can I use the same molecular weight formula as DNA?
No — RNA has a different average per-nucleotide mass than DNA (it's single-stranded with a ribose sugar), so use the RNA molecular weight calculator's formula (~320.5 g/mol per nucleotide + 159) rather than the dsDNA value.
Why does this matter for RNA experiments?
Reactions like in vitro transcription reactions or RNA-based assays often need molar (not just mass) input amounts, since molecule count — not mass — determines molar ratios and reaction stoichiometry.
What inputs does the Molarity for RNA Calculator need?
You'll need to provide: Concentration (ng/µL), Molecular weight (g/mol). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Molarity for RNA Calculator?
The Molarity for RNA Calculator applies the formula exactly as calculated — Molarity (nM) = (mass concentration in ng/µL ÷ molecular weight in g/mol) × 10⁶ — the same mass-to-molar conversion as the DNA version, applied to RNA using its molecular weight. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Molarity for RNA Calculator free to use?
Yes, the Molarity for RNA Calculator is completely free, requires no signup, and runs instantly in your browser.

Acerca de Calculadora de molaridad para ARN

The Molarity for RNA Calculator uses a real, verifiable formula — Molarity (nM) = (mass concentration in ng/µL ÷ molecular weight in g/mol) × 10⁶ — the same mass-to-molar conversion as the DNA version, applied to RNA using its molecular weight. — so results are accurate every time, not an approximation.
