Calculating Grams of Vitamin D3 from IU Powder

Based on the product name "Cholecalciferol Vitamin D3 Powder 100000 IU/g", the concentration is 100,000 IU of Vitamin D3 per gram of powder.

To find the amount of pure Vitamin D3 in 100 grams of this powder, we first calculate the total International Units (IU):
Total IU = 100 grams * 100,000 IU/gram = 10,000,000 IU.

Next, we convert IU to grams. The conversion factor for Vitamin D3 is approximately 1 IU = 0.025 micrograms (µg).
1 µg = 10^-6 grams.
So, 1 IU = 0.025 * 10^-6 grams = 25 * 10^-9 grams.

Total grams of Vit D3 = 10,000,000 IU * (25 * 10^-9 grams/IU)
Total grams of Vit D3 = 10^7 * 25 * 10^-9 grams
Total grams of Vit D3 = 25 * 10^-2 grams = 0.25 grams.

Therefore, 100 grams of this powder contains approximately 0.25 grams of pure Vitamin D3.
