Answer 1

3.35 moles.

Step-by-step explanation:

Answer 2

divide by molar mass (12.01 g)

Step-by-step explanation:

To find the number of moles of the carbon, divide by molar mass (12.01 g).

The number of moles of a substance is given as;

Number of moles =
`(mass)/(molar mass)`

To solve this problem;

since mass of carbon = 45g

Number of moles =
`(45)/(12.01)` = 3.75moles
