Gala2k [10]

Answer:

Explanation:

The formula for sodium is Na. It does not form a molecule in some way.

1 mol Na = 6.02*10^23 atoms

3.91 mol = x                                    Cross multiply

x = 3.91 * 6.02 * 10^23

x = 23.65 * 10^23

x = 2.365 * 10^24

Scientific notation is always expressed as a number 1 ≤ x < 10

amm1812

Other natural material such as clay, wood, and stones can be changed into art.

Clay is pliable and is very easy to be molded into different shapes and sizes.

Wood can easily carved into different shapes, also different patterns can be easily etched on wood.

Stones of different variety and from different geological sources are painstakingly converted into statues or portraits of different life forms and scenery.
