Question

What is the molarity of a solution with 15.0g of NaOH peer 500.0 ml solution

Answer 1

Answer: 0.75 M NaOH

Step-by-step explanation:

M = moles/L

1) convert 15.0 g to moles

15.0 g NaOH x ( 1mole NaOH/40 g NaOH) = 0.375 moles

2) now convert mL to L= 0.500L

3) plug in formula

M=0.375/0.500 = 0.75 M NaOH
