5 0

Difference Between Empirical and Molecular Formulas. The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atoms whereas a molecular formula gives the exact number of each atom in a molecule. In chemistry, we often use symbols to identify elements and molecules.

<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.

Why must a container or system be closed for equilibrium to be established?
il63 [147K]

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.

Use Boyle's Law to solve the following problem. A 400 mL sample of a gas is at 10
zubka84 [21]

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
