Explanation:</h3>
<u>Step 1: Define</u>
2.68E24 atoms Mo or 2.68 × 10²⁴ atoms Mo
<u>Step 2: Identify Conversions</u>
Avogadro's Number
Molar Mass of Mo - 95.94 g/mol
<u>Step 3: Convert</u>
<u />
= 426.966 g Mo
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
426.966 g Mo ≈ 427 g Mo
Answer:
Ecosystems have lots of different living organisms that interact with each other. The living organisms in an ecosystem can be divided into three categories: producers, consumers and decomposers. They are all important parts of an ecosystem. Producers are the green plants.

Explanation:
In living organisms, the metabolism is either anabolic or catabolic where anabolic metabolism is energy consuming and catabolic metabolism is eneegy releasesing. It should however be noted that anabolic reaction builds or biosynthesize new mollecular structures while catabolic reaction breaks down complex structure bonds into simple structures
The braking down of bonds in catabolic reations realeses energy to sustain the anabolic rection process for the formation of new bonds
Answer -C They are defined by the number of electrons.
An orbital is a function that describes the probability of finding the electron with certain energy at certain distance from the nucleus therefore, it is defined by the number of electrons.
