Math/Chemistry question

How would you set up and solve the following problem? If it took 30.0 mL of 0.50 M NaOH to neutralize 15.0 mL of HNO3, what is the concentration (molarity) of the HNO3?

Answer 1

0.0029 M of the acid

Answer 2

NaOH + HNO3 -> H2O +NaNO3
30 ml *0.5 M= 15 ml * x M

solve for x:
x * M= 30 ml *0.5 M/(15 ml )
x M=1 M

Answer 3

NaOH + HNO3 -> H2O +NaNO3
30 ml *0.5 M= 15 ml * x M

solve for x:
x * M= 30 ml *0.5 M/(15 ml )
x M=1 M

Answer 4

haha thanks!
