Answer:
Number of mole = 13.155moles
Step-by-step explanation:
One mole of a substance is equal to 6.022 * 10^23 units of that substance.
Mole of a substance can be defined according to chemistry as the mass of substance containing the same number of fundamental units
Using the formula for mole
n = m/Mm
n = number of mole
m = number of mass
Mm = number of molar mass
We are provided with some information
Given: mass of carbon to be 158g
Molar mass of C = 12.0107g/mol
Using the formula
n = m/Mm
n = 158 / 12.0107
n = 13.155 moles
