Answer:

The answer is

<h2>2.0 moles</h2>

Explanation:

To find the number of moles of an element given the number of entities contained in that element , we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

N = 1.204 × 10²⁴ lithium atoms

We have

$n = \frac{1.204 \times {10}^{24} }{6.02 \times {10}^{23} } \\$

We have the final answer as

<h3>2 moles</h3>

Name the 2 isomers of c7h16 that contain 2 methyl branches, each branch on a different carbon of the parent chain.

kupik [55]

There can be a lot of meanings for isomers. In this case, we are showing the structural isomers of C₇H₁₆. Based on the chemical formula, CₓH₂ₓ₊₂ it is an alkane. They only differ in the positions of methane branches in the parent carbon chain. Basing on the attached picture, the parent carbon chain is pentane for both isomers. But the methyl branches are on the 2nd & 4th, and 2nd & 3rd carbon for 2,4 - dimethylpentane and 2,3 - dimethylpentane, respectively.
