### Unit Conversion mol/kg to mmol/g

Hey!

Would someone be able to show me how to do the unit conversion for 1.5 mol/kg to mmol/g and mg/g?

Thank you so much!

1,5 mol/ kg = 1,5 mol/1000g = 0,0015 mol/ g = 1,5 mmol/g The number doesnt change.
For mg/g we need molar mass , without its impossible to calculate.

For mg/g the molar mass is 44.01

Also, how would I be able to convert 3.7 mmol/L to mmol/g?

44.01 Apples or what. Need correct unit. Then can use m = n* M
For converting L to g need specific gravity.

3.7 mmol/L is very diluted solution, so gravity is not distinct from 1 g / ml.

The molar mass is 44.01 g/mol

The specific gravity is for CO2 so 1.5189

### Re: Unit Conversion mol/kg to mmol/g

You need the specific gravity of the solution not from CO2. As already mentioned you can say 1 kg ~1 L but this is inaccurate.

@cheme209

3,7 mmol / l = 0,0037 mmol / g = 0,163 mg / g

3.7 mmol/L of CO2 in 1.3 M NaOH solution

convert 3.7 mmol/L to mmol/g

### Re: Unit Conversion mol/kg to mmol/g

If CO2 will dissolved in NaOH solution, then it will be converted to sodiumcarbonate.
There is no free carbondioxide left.
1,3 m NaOH has specific gravity of 1,05 g/ml
With this number you could calculate further but its hypothetic.
