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?

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

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
