Calculate the mole

0.400 g of C

To calculate the number of moles, we need to use the molar mass of carbon (C). The molar mass of carbon is 12.01 g/mol.

Mass of carbon = 0.400 g
Molar mass of carbon = 12.01 g/mol

Number of moles = Mass of carbon / Molar mass of carbon
Number of moles = 0.400 g / 12.01 g/mol
Number of moles ≈ 0.0333 mol

Therefore, 0.400 g of carbon is approximately 0.0333 moles.

To calculate the number of moles, we need to use the formula:

moles = mass / molar mass

First, we need to find the molar mass of carbon (C). The atomic mass of carbon is approximately 12.01 g/mol.

moles = 0.400 g / 12.01 g/mol

moles ≈ 0.0333 mol

To calculate the number of moles in a given mass of a substance, you need to know the molar mass of that substance. In this case, the molar mass of carbon (C) is 12.01 g/mol.

To calculate the number of moles (n) of carbon, you can use the formula:

n = mass (g) / molar mass (g/mol)

Given that the mass of carbon (C) is 0.400 g, you can plug in the values into the formula:

n = 0.400 g / 12.01 g/mol

n ≈ 0.033 moles

Therefore, there are approximately 0.033 moles of carbon (C) in 0.400 g of C.
