If it's your first encounter with chemistry, your instructor will want you to learn how to use the periodic table<span> to find the atomic mass (</span>atomic weight<span>) of an element. This number usually is given below an element's symbol. Look for the decimal number, which is a </span>weighted average of the atomic masses<span> of all the </span>natural isotopes<span> of an element. </span>

Answer:

See the answer below

Explanation:

1. Organisms produce energy for cells by chemically breaking down and unlocking the energy locked-up within food materials in a process known as cellular respiration. The unlocked energy is then utilized for the cell's metabolic activities.

2. Cellular respiration can be aerobic or anaerobic.

Aerobic respiration involves the breakdown of carbohydrates in the presence of oxygen to yield energy in the form of ATP while carbon dioxide and water are produced as by-products.

        C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP

Anaerobic respiration involves the breakdown of carbohydrates in the absence of oxygen to produce ATP and lactic acid as a by-product. The lactic acid is later oxidized to carbon dioxide and water to prevent it from building up.

       C_6H_1_2O_6 -> 2C_3H_6O_3 + ATP

3. Photosynthesis and cellular respiration are both considered metabolic processes that take place in living organisms. However, photosynthesis is peculiar only to green plants and some algae while respiration is common to all living organisms. While photosynthesis is anabolic, that is, it involves the building up of materials; respiration is said to be catabolic because it involves the breaking down of materials.

During photosynthesis, inorganic products are utilized to produce carbohydrates for plants with oxygen gas released as a by-product according to the following equation:

       6CO_2 + 6H_2O --> C_6H_1_2O_6 + 6O_2

During respiration, the food taken by living organisms is broken down to unlock the energy in it for metabolic activities according to the following equation:

     C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP

Rubidium has two naturally occurring isotopes, rubidium -85 ( atomic mass = 84.9118 amu; abundance = 72.15%) and rubidium -87 (a
son4ous [18]

Answer:

The answer to your question is: 85.458 amu

Explanation:

data

Rubidium-85   A = 84.9118 amu   abundance = 72.15%  

Rubidium - 87  A = 86.9092 amu abundance = 27.85%

Atomic weight = ?

Atomic weight = 84.9118(0.7215) + 86.9092(0.2785)

Atomic weight = 61.2538 + 24.2042

Atomic weight = 85.458 amu
