What mass of silver nitrate (AgNO3) is required to prepare 400 g of a 3.50% solution of
AgNO3

  • AP Chemistry -

    How many milliliters of a 0.9 molar HCl
    solution are needed to react completely with
    15 grams of zinc according to the following
    equation?
    ? HCl + ? Zn → ? ZnCl2 + ? H2
    Answer in units of m

  • AP Chemistry -

    3.50% AgNO3 means 3.50g AgNO3/100 g soln. You want 400 g; therefore, you will need
    3.50g x (400/100) = ?? g AgNO3.

    For your second post, this link will work all of your stoichiometry problems. Remember M x L = moles.
