How many liters of a 0.345M NaOH solution are contained in 43.5 grams of NaOH?

Question

How many liters of a 0.345M NaOH solution are contained in 43.5 grams of NaOH?

Answer 1

molar mass NAOH = 22.9898+15.9994+1.0079 =39.9971 g/mole

0.345mol/L*39.9971g/mole = 13.7989995g/L

43.5 g = X litres * 13.7989995 g/L

43.5/13.7989995 = 3.1524....... litres of 0.345 molar NaOH

You will have to do the significant figure calculation by yourself but that is the idea. Also the molar masses of the atoms changes from periodic table to periodic table so use your books periodic table.
