  1.   Look up the composition of each of the planets in our solar system, starting from  Mercury and moving out to Neptune. Write the planet and the percent of each of its  composition by volume, ignoring the trace amounts. (Wikipedia does most of this for  you.) 2.   Why does Mercury have so much hydrogen […]

SHOW ALL WORKAssume you dissolve 2.56g of malic acid, C4H605 in half a liter of water (500g). Calculate the molarity, molality, mole fraction, and weight percentage of acid in the solution.You want to prepare a solution that is 0.200m in Na2CO3. How many grams of the salt must you add to 125g of water? What […]

The calcium in a 200.0 mL sample of a natural water was determined by precip ita

The calcium in a 200.0 mL sample of a natural water was determined by precip itating the cation as CaCzoa. The precipitate was filtered, washed, and ignited in a crucible with an empty mass of 26.6002 g. The mass of the crucible plus Cao (56077 g/mol) was 26.7134 g. Calculate the cuncentration of Ca (40.078 […]

A couple of drops of water were accidentally placed on the properly folded filte

A couple of drops of water were accidentally placed on the properly folded filter paper before its mass was measured. However, in Part A.6, the CaC2O4●H2O precipitate and the filter paper were dry. As a result of this sloppy technique, will the mass of the limiting reactant be reported too high, too low, or remain […]
