In the manufacturing of computer chips, cylinders of silicon are cut into thin wafers that have a mass of
2.00 g. How many moles of silicon are in a computer chip?

Answer :

Eduard22sly

Answer:

0.0714 mole

Explanation:

Data obtained from the question include:

Mass of Si = 2g.

The number of mole of silicon can be obtained as follow:

Molar mass of Si = 28g/mol

Mass of Si = 2g

Number of mole Si =..?

Number of mole = Mass /Molar Mass

Number of mole of Si = 2/28

Number of mole of Si = 0.0714 mole

Therefore, the number of mole of silicon in the computer chip is 0.0714 mole
