In 12g of carbon-12, the molar mass of one carbon-12 atom is 12g/mol. This means that 12g of carbon-12 is equivalent to 1 mole of carbon-12 atoms. Avogadro's number states that 1 mole of atoms contains 6.022 x 10^23 atoms. Therefore, there are 6.022 x 10^23 atoms in exactly 12g of carbon-12.
To calculate the moles of each element, you need to divide each mass by the molar mass. The molar mass of carbon is 12g/mol and oxygen is 16g/mol. 12g of carbon divided by 12g/mol gives 1 mole of carbon. 32g of oxygen divided by 16g/mol gives 2 moles of oxygen.
To find the number of moles in 12g of hydrogen, we first need to determine the molar mass of hydrogen, which is approximately 1g/mol. Then we can divide the given mass (12g) by the molar mass (1g/mol) to find that there are 12 moles of hydrogen in 12g.
To convert grams of carbon to moles, divide the given mass by the molar mass of carbon. The molar mass of carbon is approximately 12 g/mol. Therefore, 28093g of carbon is equal to 28093g / 12g/mol ≈ 2341 moles of carbon.
We use the equation: Mass = Number of moles * Molecular or atomic mass Since the number of moles is 1 ("one mole of carbon-12 atoms") and the atomic mass of carbon-12 atoms is 12, hence the mass would be 12 grams. Note that the unit grams (g) is used here, as it is the SI unit for mass measurement. I hope this is useful! :)

12 g of potassium is equivalent to 0,307 moles.
12 g NF3 equals 0,17 moles.
To find the number of atoms in 12g of zinc, you would first determine the molar mass of zinc (65.38 g/mol), then calculate the number of moles in 12g (12g / 65.38 g/mol). Finally, you would convert moles to atoms using Avogadro's number (6.022 x 10^23 atoms/mol) to get the number of atoms.

To find the number of moles of atoms in 4.1 x 10^(-12) g of oxygen, you first convert the mass to moles by dividing by the molar mass of oxygen (16 g/mol). 4.1 x 10^(-12) g / 16 g/mol = 2.56 x 10^(-13) moles of oxygen atoms.
The molecular weight of sodium hydroxide is 40g/mol. To get the amount of moles, you have to divide the weight by molecular mass. 12g / 40 is 0.3 moles. This is 300 millimoles.
We use the equation: Mass = Number of moles * Molecular or atomic mass Since the number of moles is 1 ("one mole of carbon-12 atoms") and the atomic mass of carbon-12 atoms is 12, hence the mass would be 12 grams.

To determine this we must first know what the molar mass of Carbon is and that equals 12.01g. This mean for every 12.01g of Carbon, we have one mole. Therefore:48gC x (1 mole C/ 12.01g C) = 3.99 molesRounded off, in 48g of Carbon there are about 4 moles.
Molecular weight of CO2 is about 44g (12g Carbon + 32g Oxygen *2 atoms Oxygen). So that means if you are presented with 44g CO2, that means there's 12g Carbon.
