To find the number of moles of bromine gas, you can use Avogadro's number which states that there are 6.022 x 10^23 particles in 1 mole of any substance.

So, to find the number of moles of bromine gas:

Number of moles = Number of particles / Avogadro's number

Number of moles = 2.17 x 10^23 particles / 6.022 x 10^23 particles/mol

Number of moles = 0.360 moles

Therefore, 2.17 x 10^23 particles of bromine gas is equal to 0.360 moles of bromine gas.

To determine how many moles of bromine gas is equivalent to 2.17 x 10​^23 particles, you need to use Avogadro's number, which specifies the number of particles (atoms, molecules, ions) in one mole of a substance.

Avogadro's number (N​A) is approximately 6.022 x 10^23. This means that there are 6.022 x 10^23 particles in one mole of any substance.

To calculate the number of moles, divide the given number of particles by Avogadro's number:

Number of moles = Number of particles / Avogadro's number

Number of moles = 2.17 x 10^23 particles / 6.022 x 10^23 particles/mol

Calculating this gives:

Number of moles = 0.3602 moles (rounded to four decimal places)

Hence, there are approximately 0.3602 moles of bromine gas in 2.17 x 10^23 particles of bromine gas.
