If 0.45 moles of NaCl was dissolved in enough water to make 300.0mL of solutions, what is the molarity?
erica [24]
Molarity = Moles / Liters! So in this instance, if you have 0.45 moles of NaCl, and we convert 300.0 mL to 0.3 L, we would plug in M = 0.45/0.3. The answer would be 1.5 M NaCl!

 Convert the following to moles.
Luda [366]
Use dimensional analysis.
\frac{60.0 grams NaOH}{1} *  \frac{1 mole NaOH}{40.0 amu NaOH} =1.5 moles

\frac{2.73 grams NH4Cl}{1} *  \frac{1 mole NH4Cl}{53.49 amu NH4Cl} = .051 moles

Now you try converting moles to grams. All you have to do is start with MOLES  (Unlike the previous examples) over 1 then multiply that ratio by the ratio of molar mass over 1 mole. Hope this helps!
