2.258302785 x 
atoms of titanium are present in a sample containing 0.375 moles of Ti.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
To find the number atoms we need to multiply by 6.02214076 × 10^{23}.
0.375 moles x 6.02214076 ×
2.258302785 x
Hence, 2.258302785 x atoms of titanium are present in a sample containing 0.375 moles of Ti.

Production of materials and transportation are the examples of three carbon emission.
Extraction and production of purchased materials and transportation of purchased fuels are the examples of three carbon emission. Scope 3 emissions refers to all indirect emissions that occur in the chain of the reporting company that is included in both upstream and downstream emissions.
Big machineries are used for the production and extraction of materials as well as the transportation requires fossil fuels for working which releases carbondioxide gas in the atmosphere so we can conclude that production of materials and transportation are the examples of three carbon emission.
This question is very vague but I see that you posted it in Chemistry.
We can then assume that a chemical reaction is occurring that most be breaking down the building, an example being rust or corrosion. This would be environmental damage.
However, a building can be considered both a part of society and the environment depending on how you look at it. Also, it can both have environmental and social impact if its being broken down.
Coal is not a mineral. It's not a mineral because minerals are inorganic. Coal is organic because it comes from decayed living matter.
