Do 36.0 kg of carbon atoms and 3.0 kg hydrogen atoms contain the same number? Explain.

approximately, yes, since the molecular mass of carbon is 12 times the mass of hydrogen.

make that atomic mass.

To determine if 36.0 kg of carbon atoms and 3.0 kg of hydrogen atoms contain the same number, we need to compare the number of atoms in each sample.

To do this, we can use the concept of molar mass and Avogadro’s number. Molar mass represents the mass of one mole of a substance and is expressed in grams. Avogadro’s number is the number of particles (atoms, molecules, etc.) in one mole, approximately equal to 6.022 x 10^23.

First, we need to convert the masses given into moles. We do this by dividing the mass by the molar mass.

The molar mass of carbon is approximately 12.01 g/mol, and the molar mass of hydrogen is approximately 1.01 g/mol.

For carbon:
Number of moles of carbon = mass of carbon / molar mass of carbon = 36.0 kg / 12.01 g/mol

For hydrogen:
Number of moles of hydrogen = mass of hydrogen / molar mass of hydrogen = 3.0 kg / 1.01 g/mol

Next, we use Avogadro’s number to find the number of atoms in each sample. We multiply the number of moles by Avogadro’s number:

Number of carbon atoms = number of moles of carbon * Avogadro’s number
Number of hydrogen atoms = number of moles of hydrogen * Avogadro’s number

Finally, we can compare the two numbers to determine if they are the same or not. If they are equal, it means that both samples contain the same number of atoms.

Keep in mind that the molar mass and Avogadro’s number used here are approximate values, but they are accurate enough for most practical calculations.
