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

Decide whether each proposed multiplication or division of measurements is possible. If it is possible, write the result in the
Tju [1.3M]

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.
