Answer:
gold amalgamation is the mixing of gold and Mercury.
Answer:
Atomic number 29
Atomic mass 63.546 g.mol -1
Electronegativity according to Pauling 1.9
Density 8.9 g.cm-3 at 20°C
Melting point 1083 °C
Answer:
1.54×10^20 atoms
Explanation:
It's done by using the relation
N=n×L where,
N = number of entities present
n= amount of substance (mole)
L= Avogadro's constant which is 6.02×10^23
now from the question, given
n=0.000256
And L=6.02×10^23
N= 0.000256×6.02×10^23
N= 1.54×10^20 atoms
<span>1.11 g/cm³
Hope this helps! </span>
