How many molecules are found in 60 grams of KOH?

Explain step by step please

6.624× 10²³ molecules      

Explanation:

Given data:

Mass of KOH = 60 g

Number of molecules = ?

Solution:

First of all we will calculate the number of moles.

Number of moles = mass/molar mass

Number of moles = 60 g/ 56.1 g/mol

Number of moles = 1.1 mol

Now number of molecules are determine by using Avogadro number.  

1 mole = 6.022 × 10²³ molecules

1.1 mol × 6.022 × 10²³ molecules / 1mol

6.624× 10²³ molecules        

Avogadro number:

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

c. 75.7

i think that is the right

idk what the question is about
