Question

total number of electrons in 2grams of hydrogen is

Answer 1

Hey there!

One mole of any atom ➺ 6.023 ✖ 10²³ electrons

One mole of hydrogen atom ➺ 1 gram of hydrogen

2 grams of hydrogen = x

2 ✖ 1 = x ✖ 1

2=x

Number of moles =2

Therefore, Two moles of hydrogen has 2 ✖ 6.023 ✖ 10²³ electrons

2 grams of hydrogen = 12.046 ✖ 10²³ electrons

hope helped!

Answer 2

Explanation:

→1 mole of H₂ contains 6.023×10²

→One mole of H₂ atom means 1 ɡram of H₂

※then two mole of hydroɡen _→ 2ɡram of H₂

※Hence the total no. of electrons in two mole of H₂ are 12.046×10²³

※then the number of electron =12.046×10²³
