Al 2 O 3 (s)-1675.7. 50.92-1582.3. Aqueous Solutions : Ca 2+ (aq)-542.96-55.2-553.04. CO 3 2-(aq)-676.26 Assuming a 2,000 Cal daily diet, if our diet consists solely of proteins and carbohydrates, we need only about 500 g of food for sustenance—a little more than a pound. If our diet consists solely of fats, we need only about 220 g of food—less than a half pound. 65.8 g Cl2 x (1 mol Cl2/70.90 g Cl2) x (2 mol NaCl/1 mol Cl2) x (58.44 g NaCl/1 mol NaCl) = 108 g NaCl Since Cl2 makes the least amount of product, it is the limiting reactant.

Knowing the density of the acid to be 1.413 g/mL, we can calculate the weight of 1 L of 70% HNO 3 to be 1413 grams. Knowing that the solution is 70 wt % would then allow the number of grams of HNO 3 to be calculated: (0.700)(1413g) = 989.1 grams HNO 3 per liter.

In this example, multiply the grams of Na by the conversion factor 1 mol Na/ 22.98 g Na, with 22.98g being the molar mass of one mole of Na, which then allows cancelation of grams, leaving moles of Na.
