Determine the number of moles of Sulfur in 3.73 x 1035 atoms of S?

The number of moles : 6.2 x 10¹¹

The mole is the number of particles contained in a substance

1 mole = 6.02.10²³  particles

N = number of particles

n = moles

No = Avagadro's number : 6.02.10²³

3.73 x 10³⁵ atoms of S

the number of moles :

output?

explanation:

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
