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

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 = ¹ molecules

Number of moles =

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

answer: a chemical reaction
