Question: How many atoms are in 5 8 moles of helium?

How many atoms are there in 5.8 moles of helium?

Answer to Problem 1SAQ. Correct Answer: Thenumber of atoms in 5.8 mol of helium is 3.5×1024.

How many atoms are in 4 moles helium?

– So, the no of atoms in 4 moles of helium is 2.4088 × 10²⁴.

How many atoms are there in 2.5 mol of helium?

2.5mols of helium is present in 10g of helium. Explanation: 023×10^23 He atoms.

How many atoms are in 2 moles helium?

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 2 mole of helium?

If I fill up a balloon with 2 moles of helium atoms, how many helium atoms would be in the balloon? If 1 mole of atoms is 6.02 x 1023 atoms, then 2 moles of atoms would be equal to 1.20 x 1024 atoms.

What is the mole of oxygen?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

What is the mass of 2.5 moles of nickel atoms?

precisely. The mole is thus the link between the micro world of atoms, and molecules, to the macro world of grams and litres. 2.5⋅mol×6.022×1023⋅mol−1=15.06×1024⋅nickel atoms . And given that nickel has a molar mass of 58.7⋅g⋅mol−1 (how did I know this?)…can you tell us the mass of the given quantity of nickel?
