You want to prepare 1 L of a solution containing 1.00 ppm of Fe+2. How many grams of iron (II) and ammonium sulfate, FeSO4 (NH4) 2SO4 6H2O, must be dissolved and diluted in 1 L? What would be the molarity of this solution?

How many moles of al3+ ions are in 1.25 moles of al2o3

Which factor is likely to impact the possible number of compounds ?

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
