Molarity

The term molar, which describes a solution's concentration, is written as?

• M

• g

• mol/g

• g/L

Calculate the Molarity in a solution containing 40.0 g of NaCl dissolved in 500.0 ml of H2O.

• 0.08 M

• 1.37 M

• 12.5

• 0.74

Calculate the grams of NaOH present in 10.0 mL of a 2.0 M NaOH solution.

• 0.8g

• 0.3g

• 2000g

• 5g

A solution is made by dissolving 0.50 mole of NaCl in enough water to give a final volume of 400.0 mL. What is the molarity of the solution?

• 0.10M

• 1.25M

• 0.40M

• 2.33

A 0.500 M solution of NaOH, which contains 0.750 mole of solute, would have a volume, in milliliters

• 0.667 mL

• 1500ml

• 2100ml

• 1200ml

What volume, in milliliters, of 10.0 M NaOH is needed to prepare 300 mL of 2.00 M NaOH by dilution?

• 0.067 mL

• 100mL

• 60.0 mL

• 125mL

If 0.775 L of 1.00 M NaOH is diluted to 1.00 L, the resulting solution contains

• 0.225 mol NaOH

• 1.25 mol NaOH

• 0.775 mol NaOH

• 2.45 mol NaOH
