How many moles of chlorine (Cl) atoms are in a sample of 1.72 × 1022 atoms? 0.0286 mol Cl 35.0 mol Cl 1.03 × 1023 mol Cl 1.04 ×

kogti [31]

Given information : Sample of $1.72\times 10^{22} atoms$

We need to find the moles of Chlorine in the given sample.

We can say that we need to find moles from the given atoms.

Relation between mole and atom is given by : $1 mole = 6.022\times 10^{23} atoms$

Where $6.022\times 10^{23}$ is Avogadro number.

$1.72\times 10^{22} atoms\times \frac{1 mole}{6.022\times 10^{23} atoms}$

$1.72\times 10^{22}\times \frac{1 mole}{6.022\times 10^{23}}$

On solving the above equation , atoms(unit) gets cancelled out and we get 0.0286 mol.

In the given sample the moles of Chlorine (Cl) is 0.0286 mol , so option A is correct.

How do we know stars are element factories?

djverab [1.8K]

In a nutshell, stars are mainly made of hygrogen, element 1.

over time, elements got more dense as they collided and cooled, leading to other gases, metals...

then they explode, which lead to all kinds of further complex elements.

The stuff that makes up the universe a lot of it is from exploding star stuff, and the Earth was built up upon these remains and the atoms that make up organisms even could originally be from stars.
