Why 23 g of sodium and 238 g of uranium have equal number of atoms?
The number of atoms in a given mass of a substance can be determined using the molar mass. Sodium has a molar mass of approximately 23 g/mol, while uranium has a molar mass of about 238 g/mol. Therefore, 23 g of sodium corresponds to 1 mole (or approximately (6.022 \times 10^{23}) atoms), while 238 g of uranium also corresponds to 1 mole. This means that both quantities contain the same number of atoms, despite their differing masses.
How many uranium atoms are there in 6.2 g of pure uranium?
To find the number of uranium atoms in 6.2 g of pure uranium, you would first determine the molar mass of uranium, which is approximately 238.03 g/mol. Next, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the grams of uranium to number of atoms. So, 6.2 g of uranium would equal approximately 6.2 x (6.022 x 10^23 / 238.03) uranium atoms.
How many uranium atoms are there in 9.6 g of pure uranium?
9.6 grams of uranium (1 mole U/238.0 grams)(6.022 X 10^23/1 mole U) = 2.4 X 10^22 atoms of uranium
Is uranium an isotope or neutral atom?
An atom has neutrons, protons, electrons. A chemical element has isotopes. With some exceptions isotopes has no name, but a number, equal to atomic mass.
Do hydrogen and atoms have an equal number of electrons?
No. Neutral atoms of each element, including hydrogen, have a unique number of electrons, which is equal to the number of protons in their nuclei. The number of protons is the element's atomic number on the periodic table.

How many moles are 6.022 x 10 23 atoms of sodium?
6.022 x 10^23 atoms of sodium is equal to 1 mole of sodium atoms according to Avogadro's number.
How many moles of sodium are equal to 6.32 x 1025 atoms?
Quite a few. 6.32 X 10^25 atoms sodium (1 mole Na/6.022 X 10^23) = 105 moles of sodium
How many atoms in a mole of sodium?
A mole is a counting unit of molecules. Since sodium is an element and is exists by itself one mole of sodium will equal one mole of atoms or 6.02 x 1023 atoms.
How many uranium atoms are there in 9.6 g of pure uranium?
9.6 grams of uranium (1 mole U/238.0 grams)(6.022 X 10^23/1 mole U) = 2.4 X 10^22 atoms of uranium
In Uranium-238 and Uranium-234 does neither element have a charge?
Uranium-238 and uranium-234 are not "elements", but they are natural isotopes of the chemical element uranium. The atoms are neutral.
Number of electrons in a neutral atom of uranium?
A neutral atom of uranium has 92 electrons. This is because the number of electrons is equal to the number of protons in the nucleus of an atom, and an atom is neutral when the number of electrons is equal to the number of protons. Uranium has an atomic number of 92, which corresponds to the number of protons and electrons in a neutral atom of uranium.
Is uranium an isotope or neutral atom?
An atom has neutrons, protons, electrons. A chemical element has isotopes. With some exceptions isotopes has no name, but a number, equal to atomic mass.
Does the number of iron atoms in the reactants equal the number of iron atoms in the products?
no
How do you balance a equation with Na and Phosphate?
To balance an equation involving sodium (Na) and phosphate (PO4), ensure the number of sodium atoms is equal on both sides by adding coefficients. For example, in the reaction Na3PO4 + CaCl2 -> Ca3(PO4)2 + NaCl, balance by adding a coefficient of 3 in front of NaCl to ensure equal numbers of sodium atoms on both sides.
How many protons and neutrons do atoms of the same element have?
Atoms of the same element usually have the same number of protons but differ slightly in the number of neutrons. The number of neutrons are usually about the number of protons so it can be estimated as so. For example, there are two relatively common isotopes of sodium: sodium 22 and sodium 23, where the number is the total number of protons and neutrons. Sodium 22 has 11 neutrons and sodium 23 has 12 neutrons but the sodium atom has 11 protons. For further information, look up isotopes.
