Asked by Ali
what is the concentration of each substance if a solution is prepared by mixing 5.00g of NaC2H3O2 with 15.0 ml of 1.45M acetic acid and then bringing the total volume to 250.0 ml?

acetic acid = HAc
NaC2H3O2 is NaAc
mols NaAc = grams/molar mass = ?
Then mols NaAc/0.250 = ?M
mols HAc = molsL.
mols = M HAc x L HAc
volume = 0.250 L
M = mols/L.
