Question

3. What is the molarity of a solution that contains 0.50 moles of NaOH dissolved in 500 mL solution? ​

Answer 1

1M

Step-by-step explanation:

To find molarity, we use the formula
`(n)/(v)`, where n is the moles of solute, and v is the volume in liters.

This formula is fairly straightforward. When we input our values we get a formula of
`(0.50 moles)/(0.5 liters)`. Simplifying yields 1M. (Hint: Don't forget that occasionally we do have to convert between units. In this case, the 500mL was converted to liters using the known conversion factor that 1000mL= 1 liter.)
