Answer:
6.2moles of Gold
Explanation:
To solve this problem, we are going to use the mole concept approach.
Given that;
Number of atoms of gold is 3.73 x 10²⁴ atoms
Now;
In 1 mole of any substance, we have 6.02 x 10²³ atoms;
So;
If there 6.02 x 10²³ atoms in 1 mole of any substance;
3.73 x 10²⁴ atoms will contain 
= 6.2moles of Gold
Answer:
-173.15°C
Explanation:
Given data:
Temperature changes = 100 K
Temperature changes in degree Celsius = ?
Solution:
Kelvin and degree Celsius both are units of temperature.
In order to convert the degree Celsius to kelvin following equation is used.
Temperature in degree Celsius +273.15
For example;
100°C to kelvin = 100+273.15 = 373.15 K
To convert the kelvin into degree Celsius:
100K - 272.15 = -173.15°C
