Question

In an acid base titration,25.0 ml of nitric acid, HNO3, were neautralized by 28.0 mL of 0.209 mol/L calcium hydroxide, Ca(OH)2. What is the concentration of the nitric acid?

Answer 1

2HNO3 + Ca(OH)2 ==> Ca(NO3)2 + 2H2O

mols Ca(OH)2 = M x l = ?
mols HNO3 = twice mols Ca(OH)2 [Note the coefficients in the balanced equation]
M HNO3 = mols HNO3/L HNO3 = ?

Answer 2

What does M x l
I know M is the molar mass, but what is the l you wrote

Answer 3

M is the molarity. L is liters. I should have used the cap L and not the lower case l. There is no accepted abbreviation for molar mass.
