What's the first step to solving this problem? You dissolve 3.4 grams of MgO in 0.1 L of water. What is the molarity?

• Convert grams to moles

• Convert L to mL

• Convert moles to grams

• Solve for molarity

When you convert grams to moles or vice versa, you have to use the periodic table to find the ___________________ to use in your conversion.

• Molar mass

• Molar weight

• Molecular weight

• Atomic number

As you put in more solute in the solution, the concentration of the solution will...

• increase

• decrease

• stay the same
