Question

There are __ moles in 1.26 x 10^24 particles

Answer 1

Answer:

There are 2.1 moles in $1.26 \times 10^{24}$ particles.

Step-by-step explanation:

Given : $1.26 \times 10^{24}$ particles

To find : Number of moles in given particle.

Solution : Since we know,

1 mole = $6\times 10^{23}$ particles.

So, 1 particle = $\frac{1}{6\times 10^{23}}$ moles

$1.26 \times 10^{24}\text{particle}=\frac{1.26 \times 10^{24}}{6\times 10^{23}}\text{moles}$

$1.26 \times 10^{24}\text{particle}=\frac{1.26 \times 10^{24-23}}{6}\text{moles}$

$1.26 \times 10^{24}\text{particle}=0.21\times 10\text{moles}$

$1.26 \times 10^{24}\text{particle}= 2.1\text{moles}$

Therefore, There are 2.1 moles in $1.26 \times 10^{24}$ particles.
