    A. Na = 23 g/m Cl = 35.5 g/m NaCl = 58.5 g/m

    10g / 58.5 g/m =.17 mole

    .17 mole / 2.0 L = 0.086 m/L = 0.086 Molar

    B. 342 g/m 52.5/342 = 0.15 mole 0.15 mole/1.0 L = 0.15 Molar

    C. Al2 (SO4) 3= = 342 g/m 120/342 = 0.35 mole 0.35 m/10. L 0.035 Molar

    D caffeine = 194 g/m 1.75 / 194 = 0.009 mole 0.009/0.100 L 0.09 Molar
