What volume of 3.0 M NaOH contains 0.15 mole of NaOH?
A)500 mL
B)50 mL
C)5.0 mL
D)0.50 mL
E)0.050 mL

Question

Quizplus · Accepted Answer

The formula to calculate volume is:

Volume (in Liters) = Number of moles / Molarity

Number of moles of NaOH = 0.15 mole
Molarity of NaOH solution = 3.0 M

So, volume of NaOH solution = 0.15 mole / 3.0 M = 0.05 L

Convert Liters to milliliters by multiplying by 1000:

Volume of NaOH solution = 0.05 L * 1000 mL/L = 50 mL

Therefore, the answer is option B (50 mL).
