You need to learn the difference between lower and upper case letters. CO is carbon monoxide, Co is cobalt, co is company. m stands for molality. M stands for molarity = M.
H2SO4 + 2NaOH --> Na2SO4 + 2H2O
mols NaOH = M x L =2.5 M x 0.047 = 0,1175
Convert mols NaOH to mols H2SO4. 0.1175 mols NaOH x (1 mol H2SO4/2 mols NaOH) = 0.1175 x 1/2 = 0.0588.
Then M H2SO4 = mols/L = 0.0588/0.025 = ?
25.0ml of an unknown concentration of h2so4 are titrated to an endpoint with 47.0 ml of 2.5 m naoh. what is the molarity of the acid
