Answer:
602000000000000000000000
Explanation:
There are 602000000000000000000000 eggs present in one mole of eggs.
Answer:
The correct answer is A) single
Explanation:
In the case of the Bromo atom, it requires 1 electron to complete its octet, therefore it shares 1 electron with the other Bromo atom.
22.4L.
This is because the standard conversion factor for Liters is 22.4 and in the question it explicitly states liters of CO2.
Therefore, in order to convert Liters of CO2 to Moles of CO2, you'd need to use the conversion factor of 22.4.
Hope this helps!

Answer:
B) 52.000 amu.
Explanation:
- An element can have differing numbers of neutrons in its nucleus, but it always has the same number of protons. The versions of an element with different neutrons have different masses and are called isotopes.
- The average atomic mass for an element is calculated by summing the masses of the element’s isotopes, each multiplied by its natural abundance on Earth.
- Average atomic mass of P = ∑(Isotope mass)(its abundance)
<em>∴ Average atomic mass of Cr = (Cr-50 mass)(its abundance) + (Cr-52 mass)(its abundance) + (Cr-53 mass)(its abundance) + (Cr-54 mass)(its abundance) </em>
Abundance of isotope = % of the isotope / 100.
<em>∴ Average atomic mass of Cr =</em> (49.946 amu)(0.0435) + (51.941 amu)(0.8379) + (52.941 amu)(0.095) + (53.939 amu)(0.0236) = <em>52.000 amu.</em>
<em>So, the right choice is: </em><em>B) 52.000 amu.</em>
