How many moles are contained in 3.131x10^24 particles

Chemistry
1 answer:
Ede4ka [16]3 years ago
6 0

Answer:- 5.199 moles.

Solution:- To do the conversion from number of particles to moles, we use Avogadro number. Given number of particles is divided by Avogadro number and we get the moles.

Avogadro number is 6.022*10^2^3 . The calculations are given below:

3.131*10^2^4particles(\frac{1mole}{6.022*10^2^3particles})

= 5.199 moles

So, there would be 5.199 moles in 3.131*10^2^4 particles.

How does calcium and potassium react differently with water and why
tester [92]
Calcium with water:
When a metal reacts with water( cold water or hot water) then the products formed are metal hydroxide and hydrogen gas.

Metal + steam --------> Metal hydroxide + Hydrogen

Calcium reacts with cold water to form calcium hydroxide and hydrogen gas:

potassium with water.

Potassium reacts violently with cold water to form potassium hydroxide and hydrogen gas:

2K(s)+ 2H2O(l) --------> 2KOH(aq) + H2(g) + heat.
In this reaction so much heat is produced get hydrogen gas formed catches fire and burns explosively.
