Question

How many H atoms are there in 0.510 moles of H

Answer 1

No. of H atoms in 0.51 moles of H+ = 3.0713 * 10^23 atom

Step-by-step explanation:

according to the definition of mole which states that the mole is the unit of amount of substance that equals Avogadro's number"Na = 6.022 * 10^23" (i.e. one mole of O2 contains 1Na of molecules, one mole of Ca = 1Na of atoms )

So

the number of atoms in 0.51 moles of H = 0.51 * 6.022 * 10^23 = 3.0713 * 10^23 atom
