Answer 1

Step-by-step explanation:

15g•1mole/39.09g= 0.38 moles

• First you multiply 15g
• mole goes on top because it is the thing that you want to get
• look on the periodic table to kind potassium. find it's molar mass.
• that will go on the bottom. complete the equation and get your answer.

if you want to get grams instead of moles just switch the equation.
