How to find molecular formula from empirical formula?

Chemistry
1 answer:
irinina [24]4 years ago
3 0
Let's say we have the empirical formula CH4, which has the molar mass of 16.04 grams, and our molecular mass is 48.12. 
We then have to divide our molecular mass by our empirical mass. 48.12/16.04 = 3
So my multiply CH4 by a factor of 3, to get out the molecular formula C3H12

Red-blue colour ball and two white and one red colour ball attached to each other are products.

<h3>What is a limiting reagent?</h3>

The reactant that is entirely used up in a reaction is called a limiting reagent.

A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products.

A product is a substance that is present at the end of a chemical reaction.

Hence,

Galina-37 [17]
I believe the answer is C. The bonds in the compound magnesium sulfate is ionic and covalent. Magnesium sulfate is soluble in water. When the said compound is dissolved in water, it dissociates into magnesium ions and sulfate ions. However, the bonds that held together the sulfate ions is covalent.

How would you build a model that is ionized? what happens if an atom is too ionized? how would you build a model that is radioac
tatyana61 [14]
It will probably zip far from you and join itself to an adjacent molecule or atom. it gets to be distinctly radioactive when its core contains an excessive number of or an excessively couple of neutrons. Attempt to keep an indistinguishable number of neutrons and protons from you construct your iota. In the event that the awkwardness is excessively extraordinary, radioactive rot will happen.
