Answer:
the density of the electrum is 14.30 g/cm³
Explanation:
Given that:
The equilibrium fraction of lattice sites that are vacant in electrum = 
Number of vacant atoms = 
the atomic mass of the electrum = 146.08 g/mol
Avogadro's number = 
The Number of vacant atoms = Fraction of lattice sites × Total number of sites(N)
= × Total number of sites(N)
Total number of sites (N) = 
Total number of sites (N) = 
From the expression of the total number of sites; we can determine the density of the electrum;
where ;
= Avogadro's Number
density of the electrum
= Atomic mass
Thus; the density of the electrum is 14.30 g/cm³

Answer:
3D printing
Explanation:
The developments in technology, infrastructure, systems and technology mean that 3D printing will soon become a production technology. The market penetration of 3D printing would inevitably rise over time, with certain categories almost completely transitioning to 3D printing, such as digital publishing.
Answer:
Explanation:
A smaller clearance volume means a higher compression. A higher compression means better thermal efficiency. However a compression ratio too high might be troublesome, as it can cause accidental ignition of the fuel-air mix. This is the reason why Otto cycle engines have lower compressions that Diesel engines. In a Diesel engine the mix ignites by compression instead of a spark.
