To convert ng/ml to nmol/L multiply the ng/ml by 2.5 for example 50 ng/ml is equivalent to 125 nmol/L. L. Even though, there is still debate about how much we actually need, most experts agree that below 25 nmol/L (or 10 ng/ml) is considered deficient.

Remember that 1 L = 1000 mL. So converting L to mL requires multiplying by 1000 (or equivalently moving the decimal point three places to the right).

Liters to Milliliters Conversion 1 Liter (L) is equal to 1000 milliliters (mL). To convert liters to mL, multiply the liter value by 1000.

The answer is 0.001. We assume you are converting between milliliter and milligram [water]. You can view more details on each measurement unit: milliliter or milligram [water] The SI derived unit for volume is the cubic meter. 1 cubic meter is equal to 1000000 milliliter, or 1000000000 milligram [water].

The answer is 1000. We assume you are converting between micromole/liter and millimole/liter. You can view more details on each measurement unit: umol/l or mmol/l The SI derived unit for amount-of-substance concentration is the mole/cubic meter. 1 mole/cubic meter is equal to 1000 umol/l, or 1 mmol/l.

Na mass is 23, O has 16 and H is 1. Add all of these up to get the molar mass of NaOH is 40 g/mol. Now use this to convert 120 g to moles. Now take 120 grams NaOh and multiply this by 1 mol NaOH/ 40 grams NaOH.

Hence to make a 0.1 mM solution , you will need to dissolve 39.4 mg of DPPH in methanol/ethanol. A simple way to check is for 1 M in 1000 mL you need 394 g, for 1 mM you need 394 mg, so for 0.1 mM you would require 39.4 mg. However, I would suggest making a higher stock 10 mM and then dilute it before use.

The answer is 1000000. We assume you are converting between nanomole and millimole. You can view more details on each measurement unit: nmol or mmol The SI base unit for amount of substance is the mole. 1 mole is equal to 1000000000 nmol, or 1000 mmol.

Here is the reaction equation for the neutralization. One mole of NaOH reacts in equal 1:1 equivalents ratio with one mole of HCl. Therefore, for example, if the NaOH is 10ml of 6N solution, either 10ml of 6N HCl is needed, 30ml of 2N HCl or 60ml of 1N HCl would be needed.

So 1 M H2SO4= 1 x 2= 2N. Normality bof NaOH=Molarity x 1. So 1 ml. of 2N (1M) H2SO4 is required to neutralise 2 ml.

A certain amount of univalent ions provides the same amount of equivalents while the same amount of divalent ions provides twice the amount of equivalents. For example, 1 mmol (0.001 mol) of Na+ is equal 1 meq, while 1 mmol of Ca++ is equal 2 meq.

To make a 0.1M NaCl solution, you could weigh 5.844g of NaCl and dissolve it in 1 litre of water; OR 0.5844g of NaCl in 100mL of water (see animation below); OR make a 1:10 dilution of a 1M sample.
