Question

In this question

“The unit of length convenient on the atomic scale is known as an angstrom and is denoted by Å: 1 Å = 10-10 m. The size of a hydrogen atom is about 0.5 A. What is the total atomic volume in mº of a mole of hydrogen atoms ?”

all the answers i have seen have put the radius of hydrogen atom as 0.5A but the question states that the size of atom is 0.5A is there a mistake in the question itself ? please help me.​

Radius of hydrogen atom, r = 0.5 Å = 0.5 × 10-10 m

Volume of hydrogen atom = (4/3) π r3

                                             = (4/3) × (22/7) × (0.5 × 10-10)3

                                             = 0.524 × 10-30 m3

1 mole of hydrogen contains 6.023 × 1023 hydrogen atoms.

∴ Volume of 1 mole of hydrogen atom = 6.023 × 1023 × 0.524 × 10–30

                                                                  = 3.16 × 10–7 m3
