How many grams (of mass m) of glucose are in 355mL of a 5.50% (m/v) glucose solution?

You have a solution that is 18.5% (v/v) methyl alcohol. If the bottle contains 2.49L of solution, what is the volume (V) in milliliters of methyl alcohol?

A 6.00 % (m/v) NaCl solution contains 42.4g of NaCl. What is the total volume (V) of the solution in milliliters?

Help??

  1. Ok, I figured it out...

    First one is 355 * 5.5% = 19.5 g

    then, 18.5% *2.49 L *1000 (to make mL) = 461 mL

    then, 42.4/6% = 707 mL

    Now I've figured those out on my own... I'm stuck on next problem..
