Answer:
52.068 amu
Explanation:
To calculate the average atomic mass of chromium, you have to first multiply the abundance of an isotope with its mass.
49.946 × 0.0435 = 2.173
51.941 × 0.838 = 43.527
52.941 × 0.0235 = 1.244
53.939 × 0.095 = 5.124
Next, add up all of the values, and you will get the average atomic mass.
2.173 + 45.527 + 1.244 + 5.124 = 52.068 amu

Hi myself Shrushtee.
Explanation:
Wire Materials: The most common material for electrical wire is copper and aluminum, these are not the best conductors however they are abundant and low cost. Gold is also used in applications because it is corrosion resistant.

The possible options for the proposed multiplication or division of measurements are:
1. 9.0 km * 7.0 km = 63 km²; this is a correct option because km² is dimensionally correct.
3. 24 dL²/0.60 L = 0.24 L²/0.60 L = 0.4 L is a correct option since L is a unit of volume.
<h3>What are the possible options among the proposed multiplication or division of measurements?</h3>
The possible options among the proposed multiplication or division of measurements are those which are dimensionally correct.
Considering the given options:
1. 9.0 km * 7.0 km = 63 km²
This is a correct option because km² is dimensionally correct as it is a unit of area.
2. 2.0 g² * 0.043 kg is not correct since there is no unit of square mass.
3. 24 dL²/0.60 L = 0.24 L²/0.60 L = 0.4 L is a correct option since L is a unit of volume.
In conclusion, the correct measurements options are those that are dimensionally correct.
