Molarity
2,500 uM
0.0025 M
2.5 mM
2,500,000 nM
Input summary
- Mass amount: 5 mg
- Molecular weight: 1,000 g/mol
- Final volume: 2 mL
Formula
0.005 g / 1,000 g/mol = 0.000005 mol
0.000005 mol / 0.002 L = 0.0025 M
Calculated values
- Molarity: 0.0025 M
- Molarity: 2.5 mM
- Molarity: 2,500 uM
- Molarity: 2,500,000 nM
