Question
How many molecules of NO2 are present in 0.928 moles NO2?
Group of answer choices
1.54 x 10-24 molecules
5.59 x 10^23 molecules
6.49 x 10^23 molecules
1.85 molecules
Solution
To find the number of molecules in a given number of moles, you can use Avogadro's number, which is 6.022 x 10^23 molecules/mole.
Step 1: Identify the given number of moles. In this case, it's 0.928 moles of NO2.
Step 2: Multiply the given number of moles by Avogadro's number to find the number of molecules.
0.928 moles NO2 * 6.022 x 10^23 molecules/mole = 5.58 x 10^23 molecules
So, the answer is 5.59 x 10^23 molecules.
