Answer: If the gold in the crown was mixed with a less-valuable metal such as bronze of copper then this affects its density by making it to weigh even more and if it weighs more then it has less of chance to float. Observe: Drag each of the crowns into the liquid.
Explanation:
Explanation:
there is 2 nitrogen but if you mean nitrate is 6
since both the jars are kept at the same temperature the vapor pressure will be same in both the cases.
the moles of copper is 8.093 x10^10 moles
<u><em>calculation</em></u>
The moles of copper is calculated using the Avogadro's constant.
That is According to Avogadro's law
1 mole = 6.02 x 10^23 atoms
? moles = 4.872 x10^34 atoms
by cross multiplication
=[( 1 mole x 4.872 x10^34 atoms) / 6.02 x10^23 atoms]
= 8.093 x10^10 moles
