Because gravity treats all mass equally. It doesn't treat heavier objects with greater force. All objects experience the gravitational pull equally. Making the two different weights reach the ground together simultaneously despite their weight differences.

What is the final concentration if water is added to 0.50 L of a 12 M NaOH solution to make 3.0 L of a diluted NaOH solution?
SVETLANKA909090 [29]

Answer:

The answer to your question is the second option: 2M NaOH solution

Explanation:

Data

Volume 1 = 0.5 l

Concentration 1 = 12 M NaOH

Volume 2 = 3 l

Concentration 2 = ?

Formula

                     V₁C₁  =  V₂C₂

Solve for C₂

                     C₂ = V₁C₁ / V₂

Substitution

                    C₂ = (0.5)(12) / 3

Simplification and result

                    C₂ = 6 / 3

                    C₂ = 2 M

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.
