Question

How many moles of sodium hydroxide are in 20.0 mL of a 0.50 M `NaOH` solution?

Answer 1

`0.01 =` moles of NaOH

Explanation:

Molarity is a measure of moles per Liter

`M = (mol)/L` or `ML =` moles

M = 0.50 M
L = 20.0 ml or 0.020L
moles = ?

`0.50 M (0.020 L) =` moles

`0.01 =` moles of NaOH
