A pound of body fat stores an amount of chemical energy equivalent to 3500 Cal (remember, 1 Calorie = 1 kilocalorie). When sleeping, the average adult burns or expends about 0.45 Cal/h for every pound of body weight. How long, in days, would the person have to sleep continuous...
BaCl2*2H2O --> BaCl2 +2H20 4.36g ............... 3.72 ... 0.643g Convert each of the mass of product to moles. 3.72 g BaCl2 x (1 mol BaCl2 / 208.3 g BaCl2) = 0.0179 mol BaCl2 0.643g H2O x (1 mol H2O / 18.0 g H2O) = 0.0357 mol H2O Mole H2O / mole BaCl2 = 2 / 1
