Jon Frazier · Answer 1

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
