What is the molarity of a 37.50 mL sample of HNO3 solution that will completely react with a 23.70 of .0100 M NaOH?

Answer 1

Write the equation and balance it.
HNO3 + NaOH ==> NaNO3 + H2O

moles NaOH = M x L = ??

Using the coefficients in the balanced equation, convert moles NaOH to moles HNO3. Since the ratio is 1:1, that means moles NaOH = moles HNO3.

M HNO3 = moles HNO3/L HNO3.

Answer 2

thank you, I got it I think its .0632 M after dividing .00237m/.03750 L

Answer 3

I didn't find that. My calculator reads 0.00632 M.
