Answer:
545.2
Explanation:
To read a beam balance, you need to add together the numbers that each balance reads.
The first beam reads 500.
The second beam reads 40.
The third beam reads 5.2.
500 + 40 + 5.2 = 545.2
The total mass of the rock sample is 545.2.

For the drawings, please refer to the attached picture.
Explanation:
Stability of the conformers depends on the location of the groups attached to the main ring. The position of the bulkier (bigger) groups plays the most important role in conformer’s stability. If the conformer contains the bulkier group in the equatorial position, that conformer will be more stable than his twin brother with the bulkier group in the axial position. These are also drawn and attached below.
A reaction rate is generally measured in terms of amount (usually in mass) per unit volume.
