Asked by Kaylin

If there are 0.561 g of NaCl left in a beaker that originally contained 75.0 mL of saltwater, what must have been the molar concentration of the original solution? The molar mass of NaCl is 58.44 g/mol. Give your answer to 3 decimal places
Answered by DrBob222
mols NaCl left in the beaker (the same as mols in the original solution) = grams/molar mass = ?
Then M = mols/L
