1.2 x 1024 molecules are dissolved in 670 ml, what is the concentration?


Sagot :

Answer:

2.975 M is the concentration

Explanation:

1. convert 1.2 x 10^24 molecules to moles by using Avogadro's number (6.022 x 10^23 molecules in one mole) = 1.993 moles

2. convert 670 mL to L = 0.670 L

3. use the molarity equation M = [tex]\frac{mol}{L}[/tex] --> [tex]\frac{1.993 mol}{0.670 L}[/tex] = 2.975 M
