Answer:
3.75mole
Explanation:
Given parameters:
Mass of the carbon(C) = 45g
Unknown:
Number of moles of carbon = ?
Solution:
The number of moles of a substance can be found using;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of carbon = 12g/mol
Number of moles = [tex]\frac{45}{12}[/tex] = 3.75mole
