Question

How many moles are in 6.0 g of C?

Answer 1

To determine the moles of carbon in 6.0 g of C, divide the mass by carbon's molar mass (12 g/mol), giving 0.5 moles of carbon.

Step-by-step explanation:

To calculate the number of moles of carbon in 6.0 g of carbon, we can use the molar mass of carbon. By definition, one mole of carbon has a mass of exactly 12 g, which contains Avogadro's number of atoms (6.022 × 1023 atoms). Therefore, to find the number of moles in 6.0 g of C, we divide the mass of the sample by the molar mass:

Number of moles (n) = Mass (m) / Molar mass (M)

Number of moles of C = 6.0 g / 12 g/mol

Number of moles of C = 0.5 mol

So, there are 0.5 moles of carbon in 6.0 g of C.

Answer 2

Using the molar mass of Carbon, 12g/mol, we know that in 12 grams of it we have 1 mol, therefore:

12g = 1 mol

6.0g = x moles

x = 0.5 moles of Carbon in 6 grams
