The molecular formula : Cl₂O₆

<h3>Further explanation</h3>

Given

Molecular mass = 166.9 g

The empirical formula = ClO₃

Required

The molecular formula

Solution

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

<em>(empirical formula) n = molecular formula </em>

(ClO₃)n=166.9

(35.5+3.16)n=166.9

(83.5)n=166.9

n=2

(ClO₃)2=Cl₂O₆

How many nickel atoms are in a nickel coin with a mass of 3.95g
lyudmila [28]

Answer:

4.05 × 10²² atoms

Explanation:

Step 1: Given data

Mass of nickel: 3.95 g

Step 2: Calculate the moles corresponding to 3.95 g of nickel

The molar mass of nickel is 58.69 g/mol.

3.95 g × (1 mol/58.69 g) = 0.0673 mol

Step 3: Calculate the atoms in 0.0673 moles of nickel

We will use Avogadro's number: there are 6.02 × 10²³ atoms of nickel in 1 mole of atoms of nickel.

0.0673 mol × (6.02 × 10²³ atoms/1 mol) = 4.05 × 10²² atoms

Locate Lithium and oxygen on the periodic table. Briefly explain how these elements might combine to form a compound.
Mars2501 [29]
<span>Lithium atoms have one valence electron, where as oxygen atoms have six. Lithium atoms tend to give up their single valence electrons, and oxygen tends to gain two valence electrons from other atoms, like lithium. They do this so they will have filled valence shells.  hope this answers your question :)</span>
