Quick Answer: How many atoms are there in 2 moles of sodium?

How many atoms are 2 moles?

According to Avogadro’s number, 1 mol of any substance contains 6.022 × 1023 particles. As a result, 2.0 moles of helium (He) represent 2.0 mol × 6.022 × 1023 = 1.2 × 1024 atoms.

How many atoms are there in 3 moles of sodium?

3 mol Na × (6.022×10^23 atoms Na/1mol Na) = 1.807×10^24 atoms Na.

How many atoms are in 2 moles of hydrogen?

Answer: 1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.

How many atoms are there in sodium?

Then, multiply the number of moles of Na by the conversion factor 6.02214179×1023 atoms Na/ 1 mol Na, with 6.02214179×1023 atoms being the number of atoms in one mole of Na (Avogadro’s constant), which then allows the cancelation of moles, leaving the number of atoms of Na.

How many moles of sodium atom are there in sodium chloride?

Sodium chloride, commonly known as salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. So, we can say that the number of moles associated with 1.17g sodium chloride is 0.02moles.

How many molecules are there in 2 moles of h2o?

Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water. Double that for 2 moles, and there are 24.088 x 10^23 hydrogen atoms in one mole of water.

How many atoms are in 2.5 moles Na?

2.5⋅6.02⋅1023≈1.5⋅1024 sodium atoms.

How many atoms are in 3 moles?

No. of atoms = 3 × 6.022 × 10^23 = 18.066 × 10^23 atoms.
