Question

What is meant by Mole? Calculate the number of moles in 96g of SO²
​

Answer 1

Answer:

Mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.

The molar mass of  SO  

2

​  

 is 32+16+16=64g/mol.

The number of moles of SO  

2

​  

 present in 64 g of SO  

2

​  

 is  

64

64

​  

=1mol.

1 mole of any substance contains avogadro's number of molecules which is 6.0×10  

23

.

Thus, the number of molecules of SO  

2

​  

 present in 64 g of SO  

2

​  

 is 6.0×10  

23

Pls mark me as Brainiest.

Answer 2

Mole:

Mole is unit which measures the amount of the substance

$1 \: mole \: = 6.022 \times {10}^{23} \:particles$
