Answer:

Dry desert air cools much more quickly resulting in much colder nighttime temperatures.

Explanation:

The higher the moisture content in the air the harder it is to cool. Water has a much greater specific heat than dry air, retaining much more energy for each degree of temperature.

Consider a piece of gold jewelry that weighs 9.85 g and has a volume of 0.675 cm3 . The jewelry contains only gold and silver, w

AlekseyPX

Answer:

61.5096 %

Explanation:

Let the amount of gold in the jewelry = x g

Let the amount of silver in the jewelry = y g

Total mass of jewelry = 9.85 g

So,

x + y = 9.85 g .................................1

Density = Mass / Volume

Given that:

Density of gold = 19.3 g/cm³

Thus, volume is:

Volume = Mass / Density = x / 19..3 cm³

Given that:

Density of silver = 10.5 g/cm³

Thus, volume is:

Volume = Mass / Density = y / 10.5 cm³

The total volume of the jewelry = 0.675 cm³

So,

$\frac {x}{19.3}+\frac {y}{10.5}=0.675$

Or,

10.5 x + 19.3 y = 136.78875 ................2

Solving 1 and 2, we get that:

x = 6.0587 g

y = 3.7913 g

So, mass % of gold:

Mass % = (6.0587 / 9.85)×100 = 61.5096 %
