Calculate the number of miles in 2.4g of carbon

0.2 moles Carbon

Explanation:

We are required to determine the number of moles in 2.4 g of carbon.

We know that, to calculate the number of moles we use the formula;

Moles = Mass ÷ Molar mass

In this case;

The molar mass of carbon = 12 g

Therefore;

Moles of carbon = 2.4 g ÷ 12 g/mol

                           = 0.2 moles

Therefore, the moles of carbon in 2.4 g is 0.2 moles

Step-by-step explanation:

60% = 7.2/12

83% = 10/12

He improved by a supposed 23%
