A hydrologist should analyze the water for contamination
1 is an element, 2 is an compound
Energy given by carbohydrates present in one cup =
= 128 kcal
Energy given by proteins present in one cup = 
Energy given by fat in one cup = 
Total energy in one cup of cereal box = 128 kcal + 16 kcal + 18 kcal = 162 kcal
Energy present in two cups = [tex] 2 cups * \frac{162 kcal}{1 cup} *
= 324 kcal
Answer:
63.55 amu
Explanation:
(0.692 * 62.930) + (0.308 * 64.928) = 63.55 amu
Copper has two naturally occurring
isotopes: copper-63 (69.17%) and
copper-65 (30.83%).
Calculate the average atomic mass of
copper if the relative masses of the
isotope are copper 63 (62.93 amu)
and copper-65 (64.93 amu).
Cu-63 (0.6917 x 62.93 amu)
Cu-65 + (0.3083 x 64.93 amu)
Avg. mass = 63.55 amu
