When 9.36 g sodium hydroxide is dissolved in enough water to make a total volume of 965 mL, what is the concentration of the resulting solution?

The concentration of the solution is 0.242 M

Explanation:

Step 1: Data given

Mass NaOH = 9.36 grams

Volume water = 965 mL = 0.965 L

Molar mass NaOH = 40 g/mol

Step 2: Calculate moles NaOH

Moles NaOH = mass NaOH / molar mass NaOH

Moles NaOH = 9.36 grams / 40.0 g/mol

Moles NaOH = 0.234 moles

Step 3: Calculate concentration

Concentration = moles / volume

Concentration = 0.234 moles / 0.965 L

Concentration = 0.242 M

The concentration of the solution is 0.242 M

alchemy hadn't scientific methods of study, appeal to mysticism and fantasy, the knowledge of chemistry and physics were modest at that time.

alchemy was - but as new rules were discovered it either changed into chemistry or it became "unscientific".
