Answer 1

Answer:

divide by molar mass (12.01 g)

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  = $\frac{mass}{molar mass}$

To solve this problem;

  since mass of carbon  = 45g

                Number of moles  = $\frac{45}{12.01}$   = 3.75moles

Answer 2

Answer:

3.35 moles.
