molarity (M) to g/L

1 M in g/L at common molar masses

Molar mass (g/mol)1 M
58.44 (NaCl)58.44 g/L
180.16 (glucose)180.2 g/L
342.3 (sucrose)342.3 g/L
1,0001,000 g/L
5,0005,000 g/L
10,00010,000 g/L
25,00025,000 g/L

How to convert molarity (M) to g/L

  1. Enter the value in molarity (M) above. The unit is already set.
  2. Type the chemical formula (NaCl, C6H12O6) or the molar mass in g/mol. For a protein, use its mass in daltons: 66,500 for BSA.
  3. The table shows the concentration in g/L and in every other unit.

Frequently asked questions

What is the formula to convert molarity (M) to g/L?

Concentration in g/L = molarity × molar mass, so a mass concentration divided by the molar mass gives moles per litre. Convert the prefixes from there: 1 mg/mL is 1 g/L, 1 µg/mL is 1 mg/L.

What is 1 M of NaCl in g/L?

NaCl has a molar mass of 58.44 g/mol, so 1 M is 58.44 g/L.

Why do I need the molar mass?

Molarity (M) and g/L measure different things: one counts mass, the other counts molecules. The molar mass, in grams per mole, links them, so the same mass of a heavy molecule is fewer moles.
