Most of this ancient space rubble can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across.
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>
Answer:
The answer to your question is length is an extensive property
Explanation:
There are two physical properties: extensive and intensive properties.
An extensive property is a property that depends on the amount of matter.
An intensive property is a property that does not depend on the amount of matter.
