How many atoms of gold (Au) are equal to 212g of gold?
Lostsunrise [7]

Given :

Mass of gold ( Au ) is 212 gram.

To Find :

Atoms of gold present in 212 gram of gold.

Solution :

Molecular mass of gold is 197 gram.

So, number of moles of gold in 212 gram is :

n = \dfrac{212}{197} \ moles\\\\n = 1.076 \ moles

Now, we know 1 mole of any element contains 6.022 \times 10^{23} atoms.

So, number of atoms present in 1.076 moles are :

N = 1.076 \times 6.022\times 10^{23}\\\\N = 6.48 \times 10^{23}

Hence, this is the required solution.

Read the following passage.
Archy [21]

Answer is: the discovery of sub atomic particles like electrons.

J. J. Thomson discovered the electron in 1897.  

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge.  

With this model, he abandoned his earlier hypothesis (the atom was composed of immaterial vortices).  

J.J. Thomson placed two oppositely charged electric plates around the cathode ray. He did experiments using different metals as electrode materials and found that the properties of the cathode ray remained constant no matter what cathode material he used.

Tomson concluded that atoms are divisible and that the corpuscles are their building blocks (atoms are made up of smaller particles).
