24 how many moles are in 2.04 × 1024 molecules of h2o?

Sergeeva-Olga [200]

The answer is 3.39 mol.

Avogadro's number is the number of molecules in 1 mol of substance.
6.02 × 10²³ molecules per 1 mol.
2.04 × 10²⁴ molecules per x.

6.02 × 10²³ molecules : 1 mol = 2.04 × 10²⁴ molecules : x
x = 2.04 × 10²⁴ molecules * 1 mol : 6.02 × 10²³ molecules
x = 2.04/ 6.02 × 10²⁴⁻²³ mol
x = 0.339 × 10 mol
x = 3.39 mol

What examples does - Making Materials - Moving Materials - Removing Waste

Sidana [21]

Answer:

You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled

Moving Materials include aluminum foil tape, shipping tape, box tape and duct tape. Moving labels take the guesswork out of the moving process.

Which compound in each pair is more soluble in water?(b) Calcium phosphate or magnesium phosphate

Sidana [21]

larger is the value of $Ksp$ the higher will the solubility of solid in water.

What is called compound?

In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.
When the elements come together, they react with each other and form chemical bonds that are difficult to break.
These bonds form as a result of sharing or exchanging electrons between atoms.

The equation for the dissociation of a solid MX in water is given below

MX(s) ⇄ Mⁿ⁺(aq) + Xⁿ⁻ (aq)

Assume s be the solubility of MX in pure water, then the equilibrium concentrations of ions are

[ Mⁿ⁺] = s

[ Xⁿ⁻ ] = s

The expression for the solubility product constant ( $Ksp$ ) is as follows

$Ksp$ = [ Mⁿ⁺] [ Xⁿ⁻ ]

= s²

That is, larger is the value of $Ksp$ the higher will the solubility of solid in water.
