Question

the number of atoms in 0.10 grams of hydrogen gas​

Answer 1

Answer:

6.602 x 10²³ Atoms

Explanation

Data:

given mass of Hydrogen: 0.10g

Atomic mass of hydrogen: 1

Value of Avagadro's number: 6.02 x 10²³

Formula:

no. of moles =given mass x avagadro's number/atomic mass

 x = 0.10 x 6.02 x 10²³/1

 x = 6,602 x 10²³
