  1. it is pretty dilute, if you assume the density of the solution is close to 1.00, then the amount of solvent added was 250 grams. Without other information, you have to assume that.

    molarity=molessolute/.250kg

  2. mols glucose = grams/molar mass = ?
    M = mols/0.250 L = ?

    I get an answer of 0.16 = M
