13. For each of the following masses, calculate the amount (in mol) of the sample:
a) 7.83 g of lithium chloride, LiCl
b) 20.0 g of water, H2O
c) 1.3 x 103 g of calcium chloride, CaCl2
d) 2.79 kg of sodium hydroxide, NaOH
(1 kg = 1000 g)

During trial 2, what allowed you to determine that aluminum was the limiting reactant? check all that apply. all of the copper dissolved. all of the aluminum dissolved. the solution turned clear. the number of grams of copper(ii) chloride used in the reaction was greater than the number of grams of aluminum. the molar ratio of copper(ii) chloride to aluminum was greater than 3: 2, the equation’s molar ratio.

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.

How many molecules are found in 1.32 mol of nacl?
