Question

What is the total mass of 2.0 moles of diatomic hydrogen?

Answer 1

diatomic hydrogen is written as H2 (2.02 grams H2) <------- if each hydrogen atom is 1.01 grams, then two hydrogen atoms are 2.02 grams 2.0 moles H2 X 2.02 grams H2 ------------- (divide to cancel moles) = 4.04 grams/mole H2 ÷ one mole = 4.04 grams H2

Answer 2

Step-by-step explanation:

A diatomic molecule is defined as the molecule which contains two atoms.

For example, a
`H_(2)` molecule has two atoms of hydrogen.

Molar mass of a
`H_(2)` molecule is 2.0 g/mol. Therefore, calculate the mass of 2.0 moles of diatomic hydrogen as follows.

No. of moles =
`\frac{mass}{\text{molar mass}}`

2.0 mol =
`(mass)/(2.0 g/mol)`

mass = 1 g

therefore, we can conclude that total mass of 2.0 moles of diatomic hydrogen is 1 g.
