Pressure to Moles Calculator

Pressure (\( P \)):

Volume (\( V \)):

Temperature (\( T \)):

Gas Constant (\( R \)):

(Default: 8.314 J/(K·mol))

Number of Moles (mol): Number of Moles (mmol): Number of Moles (µmol): Number of Moles (nmol): Number of Moles (pmol):

1. What is a Pressure to Moles Calculator?

Definition: This calculator determines the number of moles of an ideal gas based on its pressure, volume, temperature, and gas constant using the Ideal Gas Law.

Purpose: It’s useful in chemistry and physics to quantify gas amounts in various conditions using SI units.

2. How Does the Calculator Work?

Calculations are based on the Ideal Gas Law:

\[ PV = nRT \] \[ n = \frac{PV}{RT} \]

Where (default units):

\(P\) = Pressure (Pa)
\(V\) = Volume (m³)
\(n\) = Number of moles (mol)
\(R\) = Gas constant (default 8.314 J/(K·mol))
\(T\) = Temperature (K)

Unit Conversions:

Parameter	Unit	Conversion to SI
Pressure	Pa	1 Pa
	kPa	1000 Pa
	bar	100,000 Pa
	psi	6894.76 Pa
	atm	101,325 Pa
Volume	m³	1 m³
Volume	L	0.001 m³
Temperature	K	1 K
	°C	T + 273.15 K
	°F	(T - 32) × 5/9 + 273.15 K
Gas Constant	J/(K·mol)	8.314 (default)
Moles	mol	1 mol
	mmol	10³ mol
	µmol	10⁶ mol
	nmol	10⁹ mol
	pmol	10¹² mol

Explanation: Inputs are converted to SI units (Pa, m³, K), and moles are calculated using \( n = \frac{PV}{RT} \) with \( R \) in J/(K·mol). The default units ensure accurate results.

3. Using the Calculator

Tips: Enter Pressure (default Pa), Volume (default m³), Temperature (default K), and Gas Constant (default 8.314 J/(K·mol)), then click "Calculate" to get the number of moles in multiple units (mol, mmol, µmol, nmol, pmol).
