Chapter 7: Problem 27

How many moles are equal to \(3.6 \times 10^{23}\) molecules of oxygen gas, \(\mathrm{O}_{2} ?\)

Short Answer

Expert verified
The number of moles of oxygen gas corresponding to \(3.6 \times 10^{23}\) molecules is approximately 0.6 moles.

Step by step solution

01

Understanding and applying Avogadro's Number

Avogadro's Number is a constant, given as \(6.02 \times 10^{23}\) molecules/mole. This number represents the amount of molecules or atoms in a mole of any chemical substance.
02

Calculating the number of moles

Having \(3.6 \times 10^{23}\) molecules of oxygen gas, the number of moles would be calculated by dividing the given number of molecules by Avogadro's Number.
03

Performing the calculation

Performing the division: \[ \frac{3.6 \times 10^{23} \text{ molecules}}{6.02 \times 10^{23}\text{ molecules/mole}} \]
