a packaging engineer is working on a new design for cold packs. A burst chamber in the pack will contain 14.0 mL of water, which will be released and used to dissolve ammonia nitrate.
a) If the solubility of NH4NO3 is 190g/100g H2O, what mass of this compound should be used with this amount of water?
b)The design specifications indicate that these chemicals can comprise no more than 35% of the mass of the product. What would the product weigh if it just meets these design specs?
