The 6.023 * 10²³ molecule means 384.7 grams of Vitamin D.
<h3>What is a mole ?</h3>
A mole is a universal unit used to measure large number of atoms , molecules of an element.
one mole is equal to the Avogadro's Constant.
Mole is equal to the ratio of the mass of a compound to its molecular weight
It is given that Vitamin D is present
no. of molecule = 6.023 * 10²³
6.023 * 10²³ molecule constitutes of 1 mol
1 mole is equal to the molar mass of a compound/ element
Therefore 1 mole = 384.7grams of Vitamin D
and hence 6.023 * 10²³ molecule means 384.7 grams of Vitamin D.

If you're dealing with gases, some of them could escape the container. Or, if you're dealing with liquids, there could be some outside factors playing in. In general, you need a closed system to observe a reaction accurately.
Answer:
v2 = 100 Ml OR 0.1 Liters
Explanation:
(400 Ml) (10 atm) = (v2) (40 atm)
4000 = 40v2
100 Ml = v2
Liters = ml / 1000
Liters = 100 / 1000
Liters = 0.1
