Homework Statement: Convert 50 micromolar NAD+ to ng/ml

Relevant Equations: I mole NAD+ = 660 grams
1 micromolar = 1 micromole/L
1,000,000,000 nanograms/gm

660 grams/mole for NAD+
50 micromolar is 0.00005 mole/L
0.00005 mole/L x 660 gm/mole = 0.033 gm/L
1,000,000,000 ng/gm x 0.033 gm/L = 33,000,000 ng/L
33,000,000 ng/L x 1L/1000ml = 33,000 ng/ml Is this correct?

looks OK to me

1. What is a molar conversion?

A molar conversion is a mathematical calculation used to convert between different units of measurement for a substance, typically from moles to other units such as grams or liters.

2. What is NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in all living cells that plays a crucial role in various biochemical reactions, such as cellular respiration and metabolism.

3. What does a concentration of 50 micromolar mean?

A concentration of 50 micromolar (μM) means that there are 50 micromoles of a substance per liter of solution. It is a measure of the amount of a substance dissolved in a given volume of solution.

4. How is the molar conversion for NAD+ determined at 50 micromolar concentration?

The molar conversion for NAD+ at 50 micromolar concentration can be determined by using the molar mass of NAD+ (663.43 g/mol) and the given concentration (50 μM) to calculate the number of moles present in 1 liter of solution.

5. Why is it important to know the molar conversion for NAD+ at 50 micromolar concentration?

Knowing the molar conversion for NAD+ at 50 micromolar concentration is important in various scientific experiments and calculations, as it allows for accurate measurements and comparisons between different solutions. It also helps in understanding the concentration and activity of NAD+ in biological systems.
