is 3M less or more concentrated than 9M of sulfuric acid? I think that 9M is more concentrated but I wanted to make sure.

Question

thanks

Answer 1

Of course 9M is more concentrated than 3M if both are H2SO4.
M = mols solute/L solution.
So 3M = 3 mols/L = 3*98g/1000 mL = 294g/L
and 9M = 9 mols/L = 9*98g/1000 mL=882g/L
