How many moles are in 2.04 × 1024 molecules of h2o?

Chemistry
1 answer:
EleoNora [17]3 years ago
5 0

Answer:

3.4moles

Explanation:

Given parameters:

Number of molecules = 2.04 x 10²⁴

Unknown: Number of moles

Solution

We use the concept of mole to solve this kind of problem.

A mole is the amount of substance that contains Avogadro's number of particle i.e 6.02 x 10²³ molecules

Solving

For elementary particles:

Number of moles = \frac{number of particles}{6.02 x 10^{23} }¹ molecules

Number of moles = \frac{2.04 x 10^{24} }{6.02 x ^{23} }

Number of moles of H₂O = 0.34 x 10¹ = 3.4moles

Explanation:

A. Constitutional or structural isomers have the same molecular formula but different structural formulas.

B. Conformational isomers are compounds having the same atom to atom connectivity but differ by rotation about one or more single bonds.

C. Stereo isomers are compounds having the same molecular mass and atom to atom connectivity but different arrangement of atoms and groups in space.

I. Enantiomers are stereo isomers (optical isomers particularly) that are non-superimposable mirror images of each other.

II. Diasteromers are optical isomers that are not mirror images of each other.

Both diasteromers and enantiomers are types of optical isomers which in turn is one of the types of stereo isomers.

Stereo isomers differ from conformational isomers in that the arrangement of atoms in stereo isomers is permanent while conformational isomers results from free rotations in molecules about single bonds.

Why is the greenhouse effect important to life on earth
navik [9.2K]

Answer:

Because Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. And this way, they act like the glass walls of a greenhouse. This greenhouse effect also keeps the Earth warm enough to sustain life.

Answer:

You need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal. :)
