The weight of a single sodium atom is approximately 23 atomic mass units. Therefore, a pile of 1023 sodium atoms would weigh around 23,529 atomic mass units.
The molar mass of carbon is approximately 12 g/mol. To find the mass of 7.8 x 10^18 carbon atoms, we first need to convert the number of atoms to moles by dividing by Avogadro's number (6.022 x 10^23 atoms/mol) and then multiply by the molar mass of carbon. The mass of 7.8 x 10^18 carbon atoms is approximately 1.6 x 10^-5 grams.
To find the number of atoms in 20.5 g of silver, you first need to calculate the number of moles of silver using its molar mass (107.87 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
Atomic mass- 1.01Formula- grams × (6.02 × 1023) / atomic mass = number of atoms1.00 grams H × (6.02 × 1023) / 1.01 grams = 5.96 × 1023 atoms of hydrogen
To calculate the mass of 19 atoms of copper in grams, you need to determine the molar mass of copper. The molar mass of copper is approximately 63.55 grams per mole. Then, you can use Avogadro's number (6.022 x 10^23 atoms per mole) to convert atoms to grams. So, the mass of 19 atoms of copper would be 19*(63.55/6.022e23) grams.

Neon is larger because it has more protons, electrons, and neutrons. Look at the element's Atomic Mass for an idea of its size.

The molar mass of oxygen is approximately 16.00 g/mol, so one mole of oxygen (O2) would weigh 32.00 g.

Yes, the mass of a hydrogen atom is different from the mass of an oxygen atom. A hydrogen atom has a much smaller mass compared to an oxygen atom because it only consists of one proton and, in most cases, one electron, whereas an oxygen atom has more protons, neutrons, and electrons in its structure.
To calculate the number of atoms in 4K3PO4, you would need to consider the subscripts in the chemical formula. For 4K3PO4: 4 molecules would give you 4 x 3 = 12 potassium atoms (K) 4 molecules would give you 4 x 1 = 4 phosphorus atoms (P) 4 molecules would give you 4 x 4 = 16 oxygen atoms (O) Therefore, a total of 32 atoms are present in 4K3PO4.
1 mol is equal to 6.02214179(30)×1023 molecules of the substance. The molecular weight is how much grams these molecules (6.02214179(30)×1023) weigh. Meaning g/mol.
To calculate the amount of helium in the balloon, we need to convert the mass of helium gas to moles using the molar mass of helium. The molar mass of helium is 4 g/mol. So, 0.54 grams of helium is equal to 0.54/4 = 0.135 moles of helium. Finally, we can use Avogadro's principle to convert moles to the number of helium atoms present in the balloon.
